High-purity Calcium Carbide (CaC2) specifically manufactured for industrial acetylene gas plants and chemical processing. Features high gas yield (295L/kg), consistent lump size distribution, and low impurity levels (phosphorus and sulfur) to optimize acetylene output and lower operational risks.
Our premium-grade CaC2 acetylene calcium carbide is specifically developed for large-scale industrial acetylene gas generating plants, chemical manufacturing complexes, and metallurgical foundries. Produced via high-temperature electric arc furnace smelting using high-grade coke and select lime, our calcium carbide delivers a high guaranteed gas output ($\ge 295 \text{ L/kg}$), exceptionally low impurity levels, and superior thermal stability.
Designed specifically to meet the stringent quality demands of global chemical procurement directors and gas plant engineers, this high-reactivity CaC2 acetylene raw material maximizes gas conversion efficiency while minimizing residual lime sludge formation. By reducing sludge buildup and maintenance frequency in wet and dry acetylene generators, our feedstock directly improves overall plant operational efficiency and lowers your cost per cubic meter of gas produced.
To help your engineering and process control teams evaluate compatibility, our export-grade calcium carbide complies with international standard quality benchmarks (ISO 9001 / GB209-2006):

Optimized Acetylene Yield & Energy Efficiency:
Our refined CaC2 acetylene feedstock guarantees a consistent gas evolution rate. The elevated output exceeding 295 L/kg ensures maximum extraction from every metric ton purchased, optimizing shipping and raw material budget efficiency.
Ultra-Low Phosphine (PH3) & Hydrogen Sulfide (H2S):
In chemical synthesis and high-purity gas applications, excess phosphorus and sulfur impurities cause downstream catalyst poisoning, pipeline corrosion, and safety hazards. Strict raw material selection and slag control keep our impurity levels well below industry thresholds.
Uniform Particle Size Distribution:
Screened using multi-stage mechanical sieves, our calcium carbide features minimal fines (≤5%) and consistent particle sizing (25–50mm, 50–80mm). This prevents hopper clogging, promotes predictable reaction kinetics, and maintains smooth automated feeding in continuous dry gas generators.
Reduced Environmental Sludge Impact:
High purity means lower unreacted calcium oxide and inert residue levels, resulting in less calcium hydroxide waste sludge. This lowers your hazardous waste disposal expenses and aligns with industrial environmental sustainability guidelines.
Industrial Acetylene Gas Production: Serves as the principal feedstock for high-purity dissolved acetylene gas used globally in metal cutting, oxy-acetylene welding, thermal spraying, and flame hardening.
Chemical Intermediate Manufacturing: Key starting material in the synthetic chemical value chain for producing polyvinyl chloride (PVC) resins, vinyl chloride monomer (VCM), 1,4-butanediol (BDO), synthetic rubber, and calcium cyanamide.
Metallurgical Desulfurization & Deoxidation: Utilized extensively in blast furnace ironmaking and ladle refining processes as an effective deoxidizing agent and desulfurizer to boost steel cleanliness and quality.
To safeguard product purity and prevent moisture-induced degradation during long-haul ocean shipping, we implement strict protective packaging procedures:
Heavy-Duty Steel Drum Packaging: Supplied in 50kg or 100kg hermetically sealed steel drums featuring inner moisture-resistant lining and nitrogen purge gas topping to prevent atmospheric reaction during transit.
Flexitank / Containerized Bulk Loadings: Optimized container loading layouts ensure maximum payload efficiency (22.5MT per 20ft container) while fully adhering to international maritime safety codes.
Hazard Class & Handling Compliance: Classified under UN 1402 (Dangerous when wet, releasing flammable gases). Accompanied by full MSDS/SDS documentation, REACH compliance certification, and COA (Certificate of Analysis) per batch.
Custom OEM & Private Labeling: Customized drum coloring, multilingual hazard warnings, and client brand labeling are available for contract distribution orders.
We supply factory-direct contract orders to global chemical distributors, industrial gas plants, and steel mills under FOB, CFR, and CIF incoterms. Contact our chemical trade department today to request an MSDS sheet, technical specifications certificate, or customized volume price quote.
