Barium silicate

CAS: 13255-26-0
Molecular Formula: BaSiO3
Molecular Weight: 213.41
Product description:Colorless orthogonal crystallization or powder.Soluble in cold water, hydrochloric acid. Hydrolysis in warm water. Known and hexahydrate metasilicic acid barium, 100 g water solubility of 0.17 g (15 ℃). Its aqueous solution by alkaline hydrolysis. When carbon dioxide decomposition.To refined and sufficient crushing 1 mol, silica, silica sand mixed with 1 or 2 mol, sodium bicarbonate, sodium carbonate mol, fully mixing, into the platinum crucible used in electric furnace heating to 1150 ~ 1200 ℃, was completely molten sodium metasilicate. To such of the join in the aqueous solution of 1% sodium metasilicate 15 times the molar volume of sodium hydroxide. After filtering, add 2% of barium chloride aqueous solution under stirring, which generate precipitation. The excess barium chloride must be 10%. The precipitation separation suction, water bath and dry.Used for ceramic and papermaking industry.
