High-Yield 50-80mm Calcium Carbide (CaC₂) for Industrial Applications
NEW OCEAN GROUP produces premium 50-80mm Calcium Carbide (CaC₂), an essential
inorganic chemical compound with the chemical formula CaC₂. Our product appears
as solid gray to black lumps and reacts vigorously with water to produce high-
purity acetylene gas (C₂H₂) and calcium hydroxide. The 50-80mm Calcium Carbide
size is engineered for optimal reaction kinetics, ensuring efficient gas
generation and controlled decomposition. With a guaranteed gas yield of ≥295
L/kg at 20°C and 101.3 kPa, our 50-80mm Calcium Carbide delivers exceptional
performance for demanding industrial processes. Rigorously tested to meet
GB10665-2004 standards, it features low impurities (PH₃ ≤ 0.08%, H₂S ≤ 0.15%)
and high purity (≥80% CaC₂ content).

Key Product Advantages
• Optimized Size & Efficiency: The 50-80mm Calcium Carbide granularity ensures
balanced surface area for rapid reaction while minimizing dust
• Superior Gas Yield: Consistent ≥295 L/kg gas generation outperforms industry
averages
• High Purity & Safety: Low PH₃/H₂S content minimizes corrosion risks (UN 1402,
Class 4.3 compliant)
• Robust Packaging: Nitrogen-sealed 50kg/100kg new iron drums prevent moisture
absorption
• Manufacturer Direct Pricing: Competitive FOB pricing (680/ton at scale)
• Technical Support: Dedicated R&D team for customized solutions
