Barium chloride soluble in water. On an industrial scale, it is prepared via a two step process from barite (barium sulfate): This first step requires high temperatures. In place of HCl, chlorine can be used. Barium chloride can in principle be prepared from barium hydroxide or barium carbonate. These basic salts react with hydrochloric acid to give hydrated barium chloride. Although inexpensive, barium chloride finds limited applications in the laboratory and industry. In industry, barium chloride is mainly used in the purification of brine solution in caustic chlorine plants and also in the manufacture of heat treatment salts, case hardening of steel.
