Barium chloride (barium chloride) is a binary inorganic substance belonging to the class of salts.
Chemical formula - BaCl2. Barium chloride under standard conditions is colorless rhombic crystals. Slightly soluble in alcohol, insoluble in ether. Barium chloride dihydrate crystallizes from aqueous solutions - colorless crystals with a monoclinic lattice.
Toxic, MPC 0.5 mg / m³. Barium chloride is used in the production of pigments (for example, barite yellow, cassel green and other compounds), as an additive to electrolytes in the production of magnesium, for hardening high-speed steel (in the form of melts of a mixture of barium chloride with chlorides of alkali and alkaline earth metals), as a component of ceramics , reagent for (sulfate ion), for weighting and lightening the skin in the leather industry, as a zoocide.
