Barium chloride Usage And Synthesis

Soluble barium salt Barium chloride is one of the most important soluble barium salts, it is also known as `salting barium`, the formula is BaCl2, it has colorless monoclinic and colorless cubic two crystals, monoclinic crystal turns into cubic crystal at 962℃. At room temperature it is white lustrous monoclinic crystal, odorless, bitter and salty. It is soluble in water, insoluble in acetone, ethanol and ether, slightly soluble in acid, sulfuric acid. Crystallization from aqueous solution of barium chloride often contains two crystal water. When heated to 113℃, it loses crystal water and becomes anhydrous barium chloride, it is white powder. It can be used for identification and separation of SO42- ions, purify the brine water, mainly used for the manufacture of barium salts and pigments, it can also be used as hard water softener, wool and leather industry mordant, pesticides for controlling plant pests. Preparation of industrial barium chloride is mainly used barite as material which containing high components of barium sulfate barite, coal and calcium chloride is mixed, and calcined to get barium chloride, reaction is as follows: BaSO4 + 4C + CaCl2 → BaCl2 + CaS + 4CO ↑.
Chemical properties It is colorless monoclinic crystal. (Α type) it is soluble in water, slightly soluble in hydrochloric acid, nitric acid, very slightly soluble in alcohol.
Uses (1) Barium chloride is mainly used for heat treatment of metals, barium salt manufacturing, electronic instruments, and used as water softener. 
(2) It can be used as dehydrating agent and analysis reagents, it is used for machining heat treatment Jing, see other barium chloride dihydrate. 
(3) Calibration instruments and devices, evaluation methodology, quality assurance / quality control.
