Applicazioni

Barium chloride is usually employed as a chemical reagent to precipitate soluble sulfates and also in the purification of the seawater solution. It is practiced in several applications like heat-treating baths, waste water treatment, the production of PVC stabilizers, oil lubricants, fireworks materials, hardening of steel, in the manufacture of pigments and in the manufacture of other barium salts. It is applied to prepare composites to absorb ammonia and to increase the crystallinty of polymers.

Note

It is stable under room temperatures, hygroscopic and incompatible with oxidizing agents and acids.
