Barium sulphate is a white crystalline powder. It is an important barium-containing mineral. It has strong chemical inertness, good stability, acid and alkali resistance, high density, moderate hardness, high specific gravity, high whiteness, and can absorb radiation (X-rays and Y-ray) and other advantages. It is used in a wide variety of industrial applications, including oil and gas drilling, as paint fillers and extenders, and in coatings, printing ink, rubber, papermaking, plastics, ceramics, etc.

Superfine barium sulphate is also used in high-grade marine paints, engineering plastics, powder coatings of household appliances, building materials, high-grade insulating rubber, lead acid battery, enamel glazed materials, etc.

Use of barium sulphate can change the internal structure of the brake pad, improve the porosity of the b

h temperatures and high speeds, and improves comfort.
