Precipitated Barium Sulfate

產品詳情

Product name: Barium Sulphate Precipitated

Molecular formula: BaSO4 Molecular weight: 233.39 CAS No.: 7727-43-7

Physical and chemical properties: Precipitated barium sulfate is an amorphous white powder. Non-toxic, insoluble in water and ethanol, soluble in fuming sulfuric acid, slightly soluble in boiling hydrochloric acid. Relative density 4.50, Mohs hardness 3-3.5. It is chemically stable and can be reduced to barium sulfide by co-heating with carbon. It does not change color when it encounters hydrogen sulfide and toxic gases in the air.

Functions and uses: used as raw materials or fillers for rubber, plastics, papermaking, coatings, paints, inks, insulating tapes, friction plates, batteries, pigments, cosmetics, etc. Used in rubber products, polyvinyl chloride resin fillers, reinforcing agents and weighting agents, surface coating agents for printing paper and coated paper, and sizing agents for textile industry. Clarifying agent for glass products, which has the function of defoaming and increasing gloss. It can be used as a protective wall material for radiation protection. It is also used in industries such as ceramics, enamel, spices and pigments. It is also a raw material for the manufacture of powder coatings, paints, marine primers, ordnance equipment paints, automotive paints, latex paints, and interior and exterior wall architectural coatings. It can improve product light resistance, weather resistance, chemical and electrochemical corrosion resistance and product decoration effects, and enhance coatings. impact strength. In the inorganic industry, it is used as a raw material for the manufacture of other barium salts such as barium hydroxide, barium carbonate, and barium chloride. It is used for priming and preparing printing paint when producing wood grain printing plates in the wood industry. In organic synthesis, it can be used as green pigment and color lake to produce body filler.
