Read： 1537 Time：14months ago Source：Transform the World with Simplicity

Barium carbonate is an important chemical raw material of inorganic salt, which has a wide range of uses. This article will detail the properties and uses of barium carbonate.

1. the nature of barium carbonate

barium carbonate is a white powder, insoluble in water, but soluble in acid. It has high chemical stability and thermal stability, and can be calcined and decomposed into barium oxide and carbon dioxide at high temperature. In addition, barium carbonate also has good light resistance, weather resistance and acid resistance.

2. the use of barium carbonate

1. glass industry

barium carbonate in the glass industry as a flux and fining agent, can improve the transparency and refractive index of glass, improve glass processing performance.

2.

of the ceramic industry Barium carbonate is used as an additive in the ceramic industry to increase the hardness and density of ceramics, improve the wear resistance and chemical resistance of ceramics.

3.

of the plastics industry Barium carbonate is used as a filler and modifier in the plastics industry to improve the hardness, rigidity and heat resistance of plastics and improve the processing performance of plastics.

4.

of the paint and coatings industry Barium carbonate is used as a pigment and filler in the paint and coatings industry, which can give coatings better hiding power, weather resistance and chemical resistance.

5. Chemical industry

Barium carbonate is widely used as catalyst, desiccant and desulfurizer in the chemical industry. It has high chemical stability and thermal stability and can adapt to various chemical reaction conditions.

In short, barium carbonate, as an important inorganic salt chemical raw material, has been widely used in glass, ceramics, plastics, paints and coatings, chemical and other fields, and has high economic and social value.
