High-purity acetylene calcium carbide (CaC2) manufactured via electric arc furnace smelting for continuous gas generation plants. Engineered for high volumetric output (≥295 L/kg), precise particle distribution, and low residual sludge, ensuring maximum cost efficiency and continuous operation for industrial gas utilities.
Our premium-grade acetylene calcium carbide (CaC2) is manufactured specifically to meet the high-performance demands of continuous industrial gas plants, metal fabrication facilities, and synthetic chemical complexes. Produced in high-temperature electric arc furnaces using selected low-ash coke and calcined quicklime, our chemical feedstock delivers an outstanding guaranteed gas output (≥295 L/kg), rapid reactivity, and uniform physical structure.
Engineered for chemical procurement executives and industrial gas plant operations managers, this refined acetylene calcium carbide optimizes gas collection rates while significantly reducing unreacted residue and lime sludge formation. By keeping hopper feeding smooth and minimizing maintenance downtime in both wet and dry acetylene generators, our raw material directly lowers overall plant operational overhead and improves total yield per metric ton.
Our export-grade product complies strictly with international standard benchmarks (ISO 9001 / GB209-2006) to ensure consistent quality across every batch:

Maximum Gas Evolution & Energy Efficiency:
Featuring a certified yield exceeding 295 L/kg, our acetylene calcium carbide maximizes cubic meter output per ton of raw material. This high conversion efficiency directly reduces raw material consumption and container shipping costs per unit of gas produced.
Strictly Controlled Phosphine & Sulfur Levels:
Impurities such as phosphine (PH3) and hydrogen sulfide (H2S) lead to pipeline degradation, safety risks, and catalyst poisoning in downstream chemical synthesis. Our advanced smelting purification process keeps sulfur and phosphorus trace levels well below standard industry thresholds.
Precise Granulometry for Automatic Generators:
Uniform mechanical screening prevents particle bridging and hopper blockages in modern automated feeding systems. Minimal dust fines guarantee predictable reaction kinetics and steady gas output pressure.
Lower Environmental Sludge Disposal Costs:
High chemical purity ensures less unreacted calcium oxide and inert rock residue, resulting in reduced hazardous lime sludge generation and lower environmental handling expenses.
Dissolved Acetylene Gas Production: Serves as the vital primary raw material for high-purity dissolved acetylene gas used in oxy-acetylene metal cutting, welding, flame hardening, and brazing.
Chemical Intermediate Synthesis: Essential precursor in organic synthesis for manufacturing polyvinyl chloride (PVC) resins, vinyl chloride monomer (VCM), 1,4-butanediol (BDO), and synthetic rubber.
Metallurgical Processing: Injected into blast furnace hot metal and ladle refining systems as a powerful desulfurizing and deoxidizing agent to improve steel cleanliness.
Because calcium carbide is a water-reactive substance (UN 1402, Class 4.3), we enforce strict protective packaging protocols for long-haul sea freight:
Nitrogen-Purged Steel Drums: Packed in heavy-duty 50 kg or 100 kg corrugated steel drums featuring hermetic seals and positive nitrogen gas flushing to prevent ambient air degradation and moisture contact during transit.
Dangerous Goods Safety Compliance: Accompanied by official Certificates of Analysis (COA) per batch, REACH compliance documentation, and multi-language Safety Data Sheets (SDS/MSDS).
Private Labeling & OEM Branding: Private drum color coding, custom brand printing, and customer-specific hazard warnings are available for global distributor contracts.
We provide contract volume supply to global industrial gas operators, chemical manufacturers, and trade distributors under flexible FOB, CFR, and CIF terms. Contact our export sales engineering team today to request technical samples, full spec sheets, or a competitive volume pricing proposal.
