Zhengzhou Huachuang осажденный сульфат бария 3000 Mesh

The precipitated barium sulfate is a white amorphous powder with a relative density of 4.50 (15 â„ƒ) and a melting point of 1580 ℃. Due to its high refractive index (1.63~1.65), it shows a white color and has a certain hiding power. It is almost insoluble in water, ethanol and acid, and soluble in hot sulfuric acid. It is easy to make mixed crystals with potassium permanganate, calcium carbonate or metal nitrate. It can be reduced to barium sulfide with carbon at high temperature.

It is an important basic chemical raw material. Its main uses are as raw materials or fillers for paints, coatings, inks, plastics, rubber and batteries; Surface coating agent for image paper and copper plate paper; Sizing agent for textile industry; As a clarifying agent in glass products, it can play the role of defoaming and increasing luster. It can also be used as a protective wall material for radiation protection, and also used in porcelain, enamel, dye and other industries. It is also a raw material for manufacturing other barium salts.
