Barium carbonate Usage And Synthesis

Chemical properties    Industrial product is white powder. Almost insoluble in water, soluble in alcohol, soluble in acid and ammonium chloride solution.

(1) Barium carbonate is mainly used for the manufacture of optical glass, funnels, and barium magnetic materials, the manufacture of other barium salts, ceramic, enamel, paint, welding rod feed
(2) It is important chemical raw materials for the production of funnels, magnetic materials and advanced optical glass.

Chemical Properties    Barium carbonate, BaCD3, also known as witherite,is a white powder that is soluble in acids,with the exception of sulfuric acid.It has a melting point of 174°C and is used in television picture tubes, rodenticide, optical glass and ceramic flux.
