Application:
Calcium carbide and water form the acetylene
Heating calcium carbide powder and nitrogen to form cyanamide calcium (lime nitrogen)
Calcium carbide can be used as a desulfurizer for iron and steel industry
Calcium carbide is a chemical compound with the chemical formula of CaC2
The pure material is colorless, but most samples have a color ranging from black to grayish white, depending on the grade
Its main use industrially is in the production of acetylene and calcium cyanamide
Calcium carbide is used in carbide lamps, in which water drips on the carbide and the acetylene formed is ignited
These lamps were unusable in coal mines, where the presence of the flammable gas methane made them a serious hazard
