Calcium carbide is grey, brown or black solid, purple when its purity is higher. The specific gravity is 2.22(18), melting point is 2300. It can absorb water in the air and conduct electricity. The higher its purity is, the easier it conducts. It dissolves in water, turns into acetylene and calcium hydroxide and release heat.   

Calcium carbide-2     


Production of acetylene;

Production of PVC resin;

Production of calcium cyanamide, calcium cyanamide is used as fertilizer;

Steelmaking industry: in the desulfurization of iron (pig iron, cast iron and steel);

as a fuel in steelmaking to extend the scrap ratio to liquid iron, depending on economics;

as a powerful deoxidizer at ladle treatment facilities.

Handling and Storage:

HANDLING:  Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale. Avoid abusive handling of containers which might cause denting or puncturing.  Use spark resistant tools to open containers.  Railcars, containers or other packages, fully loaded or which contain residual calcium carbide, should not be exposed to smoking materials, sparks, welding or any open flame or direct applied heating.

 STORAGE:  No smoking, fires or open lights should be permitted in storage area. Calcium carbide may be stored outdoors in unopened metal containers. Covered storage areas are recommended to prevent water entry. Indoor container storage must be well ventilated to avoid potentially flammable concentrations of acetylene and should not have sprinkler type fire suppression systems or open floor drains.  Containers should be placed on raised platforms where there is a possibility of pooled water.
