Calcium Carbide

CAS NO.: 75-20-7
Molecular formula: CaC2

Property: Grey, brown or black solid, purple when its purity is higher, the specific gravity is 2.22(18 ), melting point is 2300 , the product can absorb water in the air and conduct electricity. They higher its purity is, the easier it conducts, it dissolves in water, turns into acetylene and calcium hydroxide and releases heat.
