Barium Carbonate 25 Kg

Barium carbonate is commercially produced from barium sulfide either by treating sodium carbonate with soda ash (soda ash method) at 60 to 70 °C or by passing carbon dioxide at 40 to 90 °C.

In the soda ash process, solid or dissolved sodium carbonate is added to the barium sulfite solution and the barium carbonate precipitate is filtered, washed and dried.

Uses: Barium carbonate is mainly used for the manufacture of optical glass, funnels and barium magnetic materials, other barium salts, ceramics, enamels, paints, welding rod feed

Also used for fireworks, flame preparation, ceramic coatings and optical glass auxiliary materials.

Barium carbonate is mainly used for the manufacture of optical glass, CRT glass and barium magnetic materials and capacitors, it is also used for carburizing carbon and metal surface treatments. It is the raw material for manufacturing other barium salts and ceramics, enamels, pigments, paints, rubber, electrodes.

Also used as a rodenticide and purifying agent, oxidation catalyst. It acts as a flux, matting and crystallizing agent and combines with some coloring oxides to produce unique colors.

Its use is controversial as some claim it can leak from secrets to food and drink.

In the brick, tile, soil and ceramic industries, barium carbonate is added to clays to precipitate soluble salts (calcium sulfate and magnesium sulfate) that cause efflorescence.
