Barium Sulfate

Barium Sulphate (Natural, Precipitated)

CAS No.: 7727-43-7

Molecular Formular: BaSO4,

Molecular Weight: 233.39

Property: orthorhombic colorless crystals or a white amorphous powder. Almost insoluble in water, ethanol and acid, dissolve in hot concentrated sulfuric acid.

Usage: mainly used in the paint, ink, poster paint, cosmetics, polymer resin as fillers and chloroethane weight agent. Not only as filler in rubber products, but also as a reinforcing agent. Clarifying agent in glass making, erection defoaming effect and increase gloss. Inorganic industry for the manufacture of other barium salts such as barium hydroxide, barium carbonate, barium chloride and other raw materials. Industrial production of wood grain printing plate for printing paint primer and modulation. Organic synthesis as the production of green pigment and color lakes, physical packing.
