Precipitated barium sulfate

precipitated barium sulfate powder is a white amorphous powder with a relative density of 4.50(15℃) and a melting point of 1 580℃. Because of its high refractive index (1.63 ~ 1.65), precipitated barium sulfate powder  white and has a certain hiding power. Precipitated barium sulfate powder is almost insoluble in water, ethanol and acid, but soluble in hot sulfuric acid. It is easy to be mixed with potassium permanganate, calcium carbonate or metal nitrate. It can be reduced with carbon to barium sulfide at high temperature. Precipitated barium sulfate powder is an important basic chemical raw material. Precipitated barium sulfate powder is mainly used as raw materials or fillers for paints, coatings, inks, plastics, rubber and storage batteries; Surface coating agent for printing paper and coated paper; Sizing agent for textile industry; As a clarifier in glass products, Precipitated barium sulfate powder can defoam and increase luster. Precipitated barium sulfate powdercan also be used as a protective wall material for radiation protection, and also used in industries such as porcelain, enamel and dyes, and is also a raw material for manufacturing other barium salts.
