More Details:
We supply Barium carbonate precipitated, purity 99.2%min,premium grade quality only.

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.
