Chinese name: extinction barium sulfate

English name: Extinction Barium sulphate

Molecular formula: BaSO4

Molecular weight: 233.39 (according to the 1979 International Atomic Weight Scale)

Properties of matting barium sulfate

White powder, relative density 4.0-4.6, non-toxic, tasteless, insoluble in water, acid, alkali and organic solvents, only soluble in strong acid and concentrated sulfuric acid.

Characteristics of matting barium sulfate

Microaerial extinction barium sulfate has good dispersion, excellent light resistance, weather resistance and acid resistance, and good extinction effect. In flat, semi smooth and matt powder coatings, reducing the amount of matting agent, good flatness, no impurities, can reduce the cost. It has good hiding power, and as the carrier of pigment, it can effectively disperse the pigment to obtain uniformity. The characteristics of fine crystal structure and high refractive index make the color more rich and full. It does not react with any gas. Therefore, it is a weather and corrosion resistant product.

Use of matting barium sulfate

Micro aviation extinction sulfuric acid is used as supplementary filler, and can be used for acid resistant rubber products and general products. It can also be used as surface coating agent, sizing agent, weighting agent, as well as plastic, paint, rubber, paint, ink, ceramics, battery, enamel, etc.
