Inorganic Salt Barium Sulfate with CAS No. 7727-43-7
Precipitated barium sulphate is produced by domestic advanced chemical precipitation process, with superior physical properties, less mechanical impurities, and extremely fine fineness. It is amorphous white powder, non-toxic, insoluble in water, soluble in fuming sulfuric acid,slightly soluble in boiling hydrochloric acid and has stable chemical properties. It is co-thermally reduced with carbon to yttrium sulfide. In the air, it won't change color when met hydrogen sulfide or toxic gases. It is a product with higher quality of similar products in China. Can absorb X-rays and give the material a high density and surface finish. Colorless orthorhombic crystals or white amorphous powder, relative density 4.50 (15), melting point 1580, almost insoluble in water, ethanol and acid, soluble in hot sulfuric acid, easy to agglomerate when dry.
