Product Content

MSDS 1007 Barium carbonate precipitated, Industrial Grade

Barium Carbonate is odorless, white crystal powder, Almost insoluble in water.

Barium carbonate is made from barium sulfide (natural ore, barite) by treatment with sodium carbonate at 60 to 70 °C (soda ash method) or by passing carbon dioxide at 40 to 90 °C. In the soda ash process, solid or dissolved sodium carbonate is added to barium sulfide solution, and the barium carbonate precipitate is filtered, washed and dried.
