Calcium carbide
From GAWDAwiki
Calcium carbide, known as CaC2, is an alkaline Earth carbide obtained in the pure form as transparent crystals that decompose in water; used to make acetylene gas. [1]
Calcium carbide is violet-red color that appears blue-violet when it is fractured. It is decomposed readily by atmospheric humidity and has a characteristic garlic-like scent. On contact with water or in damp surroundings, acetylene is formed and explosive atmospheres can be produced.[2]
Calcium carbide is also used as a desulfurizer in the steel manufacturing process.[3]
