Precipitated Barium Sulfate
Molecular formula: BaSO 4
H.S. Code: 2833270000
EINECS No: 231-784-4
CAS No.: 7727-43-7
Description:
Our precipitated barium sulfate is super-fine powder, made from high quality barite, which is white powder with specific gravity 4.50(15 ℃ ). It can be soluble in hot concentrated sulfuric acid, but cannot be soluble in water/ organic solvent / acid. The end products have good dispersibility, high whiteness, nice covering power, stable chemical properties.
