Molar Weight: 197.34 g / mol
Melting point: 811 ° C
Boiling point: 1450 ° C
Other names: Carbonic Acid, Barium salt
Chemical formula of BaCO3 is poisonous, granular and white crystalline. They are more commonly known as Viterit in Europe. It has an important usage area for barium compounds. It has low hardness and absorbable X-rays. The -CO3-ion here reacts with hydrogen ions to reduce the acidity of the solution and increase the ph value.
Production and Reactions
Barium carbonate reacts with acids such as hydrochloric acid to form soluble salts such as barium chloride:
BaCO3 (s) 2 HCl (aq)? BaCl2 (aq) CO2 (g) H2O
The molten or hot barium chloride solution can be electrolyzed to produce pure barium. Barium carbonate; Barium sulphate solution is added to the appropriate CO2 by the addition of a solid or dissolved sodium carbonate at (60-70) ° C, and the barium carbonate precipitate is filtered. (soda ash method)
The use of barium material and its compounds in this sector is common.
It is an additive in glaze production in glass sector.
They are used in the production of various and special glass and also in the production of optical glass in the production of color TV.
They serve as carbon carriers in cleaning metal surfaces.
