Calcium Carbide 15-25 MM

Calcium Carbide Stones are a primary and unprocessed bulk form of Calcium
Carbide, typically ranging in size from 15mm to 25mm. They are produced
directly in an electric arc furnace at extreme temperatures (~2,200°C) from a
mixture of lime and coke. This lump form is the foundational product from which
other forms like granules or powder are derived, and it is primarily used in
large-scale industrial applications such as acetylene generation for gas
welding/cutting and as a desulfurizing agent in steelmaking. Wanding provides
this high-quality, industrial-grade product to meet robust industrial demands.
Shape: white crystals, black lumps, purple or gray cross-section for industrial
products
Available particle size: 1-4mm, 4-7mm, 7-15mm, 15-25mm, 25-50mm, 50-80mm, 80-
120mm.
Gas production: 210L/KG, 230L/KG, 260L/KG, 295L/KG, depending on the size of
the particles. 
Physicochemical Properties: The solid of the ore is brown or black solid, the
pure product is white crystal (containing CaC2 is purple). Density 2.22g/cm3,
melting point 2300℃ (with CaC2 content), immediately react violently with
water to generate acetylene and release heat, calcium carbide content of
different melting point will also change.
