Product Description

White barium carbonate for ceramic 99%

Product Description
Barium carbonate (BaCO3), also known as witherite, is a chemical compound used in rat poison, bricks, ceramic glazes and cement.

Preparation
Barium carbonate is made commercially from barium sulfide either 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. In the barium carbonate molecule, two oxygen atoms gain one electron each from Ba atom
