Barium Chloride
Explanation:
Barium chloride, of the chemical formula BaCl2, is a substance widely used in the quenching metallurgy industry to increase the hardness of ferroalloys and/or steels (heat treatment of metals). It is also used in barium salt industries and sulphate elimination industries. It is a white solid at room temperature, conducts liquid electric current, and is therefore an ionic substance.
