Calcium Carbide: Chemical ID, CAS, Formula, HS Code Database

Product Identification
Product Name & IUPAC Name	The product is commonly referred to as Calcium Carbide in the industrial and chemical supply chain. The International Union of Pure and Applied Chemistry (IUPAC) designates the compound as calcium ethynediide, which directly reflects its carbide structure and reactivity.
Chemical Formula	CaC2 Raw material and catalyst selection influence downstream consistency for this formula. In technical production, the stoichiometry is managed through precise batching of finely prepared calcium oxide and carbon. Formulaic performance in process depends on the actual feedstock carbon content and purity screening of lime. Typically, the solid is handled as a granular or lumpy product with calcium and carbon incorporated according to batch charge control procedures.
Synonyms & Trade Names	Synonym catalogues and purchasing contracts typically include: Calcium acetylide, CaC2, Carbide, and Dicyan. Regional trade names can reflect the form—lump, granular, technical, metallurgical. Some product lines differentiate grades by down-stream acetylene generation rate or impurity level; naming varies across markets depending on intended end use.
HS Code & Customs Classification	International trade relies on concerted classification. Calcium carbide typically clears customs under HS Code 284910. Actual import documentation may vary by country; end-use declaration often distinguishes technical, metallurgical, or reagent grades. Exporters document both the code and the grade-dependent product description, since acetylene yield and physical granulation affect customs oversight and destination market compliance.

Manufacturer Commentary on Key Identifiers

Product identification across all sales agreements requires careful harmonization with both international chemical registration (CAS: 75-20-7) and customs documentation. Chemical code errors in shipping papers complicate regulatory inspections and can hold back consignments at port, so we maintain regular staff competency checks on regulatory updates for destination markets.

Proper assignment of trade names and synonyms allows technical teams to align batch release documentation and marketing claims. In practice, the product’s actual reactivity depends less on nomenclature and more on internal batch standardization—particularly in the control of phosphate, sulfur, and iron impurities that originate from the lime and coke feed streams.

Processing teams keep detailed logs of raw material batches and achievable process chemistry, noting deviations in quicklime purity and granular handling efficiency, as these factors impact the downstream performance and identity preservation through storage and transport chains.

Customers often specify formula, grade, and classification details on procurement contracts. Invoicing and logistics teams work closely with plant operators to update documentation according to the observed product grade at the point of shipment, thereby managing regulatory risk and minimizing customs delays associated with incorrect classification.

Technical Properties, Manufacturing Process & Safety Guidelines for Calcium Carbide

Physical & Chemical Properties

Physical State & Appearance

In the manufacturing environment, calcium carbide typically enters the process as grey lumps or granules with visible crystalline structure. The physical form depends on the crushing and sizing settings at the production facility. Finer grades for acetylene-generating applications appear dustier and require more careful dust control. Most industrial grades emit a faint garlic-like odor due to trace phosphine and hydrogen sulfide. Melting and boiling points are both high and not encountered in normal use, as decomposition takes place before reaching these temperatures. Measured density and appearance tend to vary with batch porosity, particle size, and impurity trapped during cooling. Bulk storage bins are designed to handle the abrasive and reactive nature of the material, as it reacts vigorously with water vapor to release acetylene.

Chemical Stability & Reactivity

Reactivity with moisture forms the fundamental risk and value proposition of calcium carbide. Contact with water—liquid or vapor—instantly releases acetylene, governed by the reaction's surface area and purity. The source of reactivity in a production batch is closely related to particle size, exposure to humidity, and retained free lime or oxidized species formed during storage or handling. Stabilizers are not typically added, as the value of the product lies in controlled reactivity.

Solubility & Solution Preparation

Calcium carbide does not dissolve in water; it reacts with it. Manufacturers monitor soluble by-products, mostly calcium hydroxide and trace impurities, based on the application. For accurate acetylene yield, water introduction and agitation are designed specifically for each grade in downstream processes.

Technical Specifications & Quality Parameters

Specification Table by Grade

Grade	Intended Use	Key Parameters
Technical Grade	Acetylene Generation	Size fraction, acetylene yield, impurity content
Metallurgical Grade	Steel Desulfurization	Coarseness, specific impurity targets
Special Grades	Chemical Synthesis	Customization per client or regulatory need

Exact composition, size ranges and limits for impurities such as phosphide, sulfide, and free lime vary according to region, end use, and customer requirements. Typical values depend on application requirements.

Impurity Profile & Limits

In production, impurities arise from raw material feedstock (limestone and coke quality), furnace atmosphere, and in-furnace reactions. Manufacturers monitor total phosphorus, hydrogen sulfide evolution rate, and trace silicon or iron compounds. Phosphine levels drive odor issues and user acceptance. Final impurity limits are agreed upon with the customer or reflect national quality standards.

Test Methods & Standards

Routine evaluation in the factory follows established local or international standards for acetylene yield, particle size distribution, and contaminant assays. Deviations from method protocols are common depending on available equipment and batch size. The final release standard is subject to internal quality control criteria and customer requirements.

Preparation Methods & Manufacturing Process

Raw Materials & Sourcing

Manufacturing begins with strict limestone and coke selection. Limestone quality directly controls silicate, iron, and phosphate impurity introduction. Coke purity, particle size, and ash content influence furnace operation and slag properties. Raw materials are sourced regionally to optimize cost, logistics, and regulatory compliance.

Synthesis Route & Reaction Mechanism

Production proceeds by heating a stoichiometric mix of lime and coke above 2000°C in an electric arc furnace. Process routing is decided based on energy efficiency, slag management, and available infrastructure for offgas capture. The reaction's exothermic control is critical; runaway conditions generate excessive fines or off-spec carbide.

Process Control & Purification

Continuous operation demands close control of charge composition, electrode integrity, furnace temperature, and atmospheric gas balance. Post-cooldown, mechanical handling separates metallic carbide from furnace slag. Purification often relies on screening, magnetic separation, and offgas filtering. Experience shows that environmental controls for dust, water vapor, and fugitive emissions strongly affect worker safety and product consistency.

Quality Control & Batch Release

Each batch undergoes sampling for acetylene evolution, particle size, and contaminant load. Adjustments occur based on the application: tighter controls in grades destined for acetylene lamps, or relaxed parameters for metallurgical purposes. Consistent operational procedures and statistical monitoring maintain batch-to-batch reproducibility. Release decisions depend on meeting internal specifications and contractual commitments.

Chemical Reactions & Modification Potential

Typical Reactions

The central industrial reaction involves water addition to generate acetylene and calcium hydroxide. Downstream users may introduce the product into reactions forming vinyl compounds, acetylene black, or organic intermediates.

Reaction Conditions

Temperature, agitation, and water purity impact acetylene generation. In lab settings, carefully metered water and catalytic additives—if needed—improve yield or purity. For large-scale metering, oversized reaction vessels and venting systems accommodate the exothermic nature and volume of evolved gas.

Derivatives & Downstream Products

Calcium carbide serves as a building block for acetylene-based chemicals and some specialty alloys. Purity demands for derivatives reflect ultimate product application—pharmaceutical intermediates, polymer monomers, or fine chemicals each draw on grades with specific impurity loads and particle size.

Storage & Shelf Life

Storage Conditions

Moisture exclusion forms the basis of every industrial storage recommendation. Production experience shows that humidity above certain thresholds accelerates surface hydration, leading to powdering, caking, and loss of acetylene yield. Warehousing employs sealed drums or silos lined with materials compatible with calcium carbide—typically steel with corrosion-resistant coatings. Removal from direct sunlight and protection from rain or leaks is standard.

Container Compatibility

Best practice keeps the material in containers free of moisture, rust, or organic debris. Incompatibility with copper, bronze, and lead-bearing alloys is documented due to risk of acetylene-promoted corrosion or explosive by-products. Most facilities design transfer and storage systems for rapid and complete aeration after loading.

Shelf Life & Degradation Signs

Shelf life depends on grade, storage discipline, and environmental control. Large lumps retain reactivity longest, provided internal moisture is absent. Fines and cracked particles experience faster deactivation. Powdery residues and suppressed acetylene generation flag product aging or compromised storage.

Safety & Toxicity Profile

GHS Classification

Calcium carbide receives hazardous material classification due to flammable gas release in contact with water and irritant/corrosive effects on skin and eyes. Production staff and logistics partners operate under international transport rules for dangerous goods and hazardous substances.

Hazard & Precautionary Statements

Direct exposure may cause chemical burns or irritation. Acetylene released from wet carbide poses explosion risk in confined or poorly ventilated spaces. Precautions in the plant include sealed personal protective equipment, moisture sensors, and strict segregation from fuel or ignition sources. Maintenance work involving open hoppers or conveyors includes purging and atmosphere monitoring.

Toxicity Data

Toxicity concerns stem mainly from by-products such as phosphine and hydrogen sulfide, which can accumulate in poorly vented storage or use environments. Manufacturers install exhaust and scrubbing units as a standard engineering control, given the acute toxicity of these gases.

Exposure Limits & Handling

Handling policies focus on dust suppression, avoidance of moisture ingress, rapid detection of acetylene evolution, and immediate containment of spills. Occupational exposure limits for airborne acetylene and phosphine by-products reflect the most recent regulatory data; plant management monitors and maintains workplace concentrations below these values through ventilation, process enclosure, and routine training.

Supply Capacity & Commercial Terms: Calcium Carbide

Production Capacity & Availability

In calcium carbide manufacturing, installed capacity links directly to furnace configuration, ore supply logistics, and sustained power availability. Consistency of production hinges on uninterrupted access to lime and coke, as well as stable electric arc furnace operation. Inventory buffers may absorb short-term outages, but contract volume support for ongoing customers remains prioritized over spot allocations. For special-size or high-purity grades, line availability rotates based on campaign scheduling and downstream demand.

Lead Time & MOQ

Standard-grade calcium carbide lead time reflects real furnace throughput and stabilization after scheduled maintenance. Minimum order quantity rests on bulk logistics efficiency and safe transport regulations for packaged goods. Custom grade or granular specifications extend lead due to screening, dust containment, or multi-batch blending requirements. Tight shipping windows may be accommodated with prior slot reservation or annual procurement planning.

Packaging Options

Granular and lump-grade calcium carbide typically loads in sealed drums, sturdy steel cylinders, or moisture-tight big bags, depending on reactivity and end-use packaging requirements. Packaging integrity must account for gas release risks, transit vibration, and moisture exclusion demands at customer sites. Weight increments vary by jurisdictional transport regulations and site handling constraints. Packaging configuration may be tailored to downstream automation or feeding preferences.

Shipping & Payment Terms

Due to UN-classified handling and regulatory inbound storage needs, shippers strictly follow classified packaging and documentation standards. Payment terms often reflect supply stability and customer history, with new buyers evaluated for credit risk and documentary compliance. FOB, CFR, or DAP terms apply, subject to route-specific safety and offloading requirements, often coordinated with downstream production scheduling.

Pricing Structure & Influencing Factors

Raw Material Cost Composition & Fluctuation Causes

Calcium carbide pricing structure depends heavily on cost outlays for metallurgical coke, quicklime, and electricity. Electricity forms the largest cost portion—especially in energy-intensive direct arc production. Shortages or seasonal price spikes in fuel and power directly push manufacturing costs. Variability in ore grade, coke ash content, and local power tariffs all affect cost structure. Raw material contract arrangements, trading mechanisms, and location-specific supply chains magnify these influences.

Product Price Difference Explanation

Price dispersion among calcium carbide grades arises from several technical levers: core grade differentiation (gas yield, impurity profile), purity (phosphorus, sulfur, metallic inclusions), and packaging standard. Grades selected for ethylene or PVC production demand stricter impurity cutpoints compared to acetylene lighting or desulfurization applications, and associated post-processing steps affect final cost. Packaging that assures moisture resistance or accommodates automation increases per-ton price, as does compliance with local or international certification schemes.

Application Fields & Grade Selection Guide — Calcium Carbide

Application Fields & Grade Matching Guide

Industry Applications

The main uses for calcium carbide stretch across several sectors with performance rooted in grade selection and control of specific contaminant levels. The chemical industry consumes bulk tonnage in acetylene generation for welding gas production, organic synthesis, and intermediate manufacturing. Steelmakers turn to selected grades for desulfurization and deoxidation. Carbide lamps require technical grades formulated for stable gas yield and management of evolved byproducts. Agrochemical production applies targeted grades for synthesis of specific chemicals.

Grade-to-Application Mapping

Application	Standard Grades	Critical Characteristics
Acetylene Generation (Welding, Chemical Synthesis)	Technical, Commercial, High-Purity Grades	Low phosphorus (P), low sulfur (S), controlled moisture and dust content
Steelmaking (Desulfurization, Deoxidation)	Metallurgical Grade	Granulometry for feeding systems, CaC2 content, controlled trace metals
Carbide Lamp	Lamp Grade	Consistent granule size, predictable gas yield, low residue
Specialty Chemical Synthesis	Fine Chemical Grade	Tight impurity profile, batch-to-batch consistency

Key Parameters by Application

• CaC₂ content: Acetylene output and heat of reaction depend directly on the active ingredient content. Lower grades result in reduced and unpredictable yields.
• Impurities (P, S, As, heavy metals): Specifications shift with intended use. Welders and chemical plants push for tighter impurity limits versus less sensitive metallurgical applications.
• Granulometry: Lamp and gas generator grades rely on particle distribution for uniform reactivity and safe handling. Steel grades often call for coarse fractions, balancing reactivity and flow.
• Batch Consistency: End users in synthesis and lamp applications demand consistent reactivity curves. Production is managed to minimize intra-lot and inter-lot variation.

How to Select the Right Grade

Step 1: Define Application

Define the purpose of use before involving procurement or technical teams. Acetylene for welding, chemical feedstock, or lamp operation each carries different reactivity, yield, and impurity requirements. Steel producers need reliability for ladle injection, which highlights particle size and rapid reactivity over maximum purity.

Step 2: Identify Regulatory Requirements

Local and industry-specific rules often set baseline impurity, labeling, and transport needs. For example, acetylene used in pharmaceutical synthesis may be subject to higher regulatory scrutiny compared to product earmarked for metal cutting. Production lots can be tailored to meet relevant regional standards as specified by end users or authorities.

Step 3: Evaluate Purity Needs

Analyze downstream requirements and select from available grades that fit critical impurity tolerances and moisture limits. High-purity and technical grades suit chemical synthesis applications. Metallurgical users focus on minimizing elements that reduce performance inside the ladle rather than absolute chemical purity.

Step 4: Consider Volume & Budget

High-purity grades involve greater raw material sorting, extended reaction residence times, and tighter process control, which are reflected in cost. Volumes above several hundred tons typically justify custom production runs, where plant scheduling and process route selection optimize both cost per ton and property control.

Step 5: Request Sample for Validation

Operational performance must be validated under the actual process conditions. Standard procedure includes qualification sampling, customer-specific certificate release, and on-site or lab-based assessment of actual acetylene yield, residue characteristics, and reactivity profiles.

Production & Quality Management Insights

Commercial calcium carbide grades are manufactured through the reaction of lime and coke in electric arc furnaces. Raw material quality tracking begins with input analysis, as coke and lime impurities translate directly to product trace contaminants. Furnace operating parameters and tap-to-granulation strategies affect CaC₂ yield and particle distribution. Regular in-process controls check for unreacted lime and coke, granule friability, and free moisture. End-of-line product release criteria are set according to product grading, final acetylene yield, impurity content, and physical form. Ongoing quality management targets not only compliance with customer specifications but repeatable batch-to-batch performance, increased yield efficiency, and control of off-spec byproduct flows to minimize downstream issues in customer operations.

Trust & Compliance: Quality Certifications & Procurement Support for Calcium Carbide
