Barium chloride 2-vodn.
Chemical formula — - BaCl2. Barium chloride under standard conditions represents colourless rhombic crystals. It is slightly soluble in alcohol, is not soluble on air. From water solutions the barium chloride dihydrate — - colourless crystals with monoklinny lattice crystallizes.
It is toxic, maximum concentration limit of 0,5 mg/m ³-. Barium chloride is applied in production of pigments (for example, barytic to zhyolta, kasselevy greens and other connections), as additive in electrolytes when receiving magnesium, to tempering of quick cutting steel (in the form of barium chloride mix fusions with chlorides of alkaline and shchyolochnozemelny metals) as ceramics component, reactant on (sulfate ion), for weighting and clarification of skin in the tanning industry as zoocide.
