Barium sulfate is a common material in chemical industry. In industry, barium sulfate is divided into many kinds: precipitated barium sulfate, ultrafine barium sulfate, high-gloss barium sulfate, extinction barium sulfate, ultrafine modified barium sulfate. Let Xiaobian introduce a variety of barium sulfate knowledge below!



I precipitated barium sulfate:

The appearance is white amorphous powder with a relative density of 4.50 and a melting point of 1 580 ℃. It is almost insoluble in water, ethanol and acid, soluble in hot sulfuric acid. It is an important basic chemical raw material,

Main uses: used as raw materials or fillers for paints, coatings, inks, plastics, rubber and batteries; surface coating agent for printing paper and copper plate paper; sizing agent for textile industry; clarifying agent for glass products, porcelain, enamel and dye industries, and other raw materials for manufacturing other barium salts.



II superfine barium sulfate:

Narrow particle size distribution and high chemical stability. Barium sulfate content of more than 98%, it has high whiteness, no black spots, no impurities, good dispersion, and has good wettability, excellent acid resistance, high temperature resistance, corrosion resistance. Can significantly improve the hardness and wear resistance of products.

Main uses: used in various coatings, plastics, rubber, paint, ink and other industries. Can be used for acid-resistant rubber products and general products. It can also be used as a surface coating agent, sizing agent, weighting agent, and also used in papermaking, ceramic batteries and other fields.



III high gloss barium sulfate:

Good dispersion, high whiteness, good leveling. It has excellent light resistance, weather resistance and acid resistance. It has good chemical inertness and moderate surface energy, so that it has good dispersion and affinity with other media as a functional filler. And with all the color has good compatibility. It is an environmentally friendly material that can absorb harmful rays.

Main uses: supplementary fillers, used in plastics, coatings, rubber, paints, inks, ceramics, batteries, enamels, etc. It works well in powder coatings.



Ⅳ extinction barium sulfate:

Good dispersion, excellent light resistance, weather resistance and acid resistance, good matting effect. In flat, semi-gloss, matte powder coatings, reducing the amount of matting agent, good flatness, no impurities, can reduce costs. It has a good hiding power, at the same time as the carrier of the pigment to make the pigment efficient dispersion and obtain uniform, fine crystal structure characteristics and high refractive index, so that the color is more rich and full. Does not react with any gas.

Main application: for paint and powder coating. Can also be used in paint, plastic, rubber, ink, ceramics.



v ultrafine modified barium sulfate:

It is a special product. It has the characteristics of good dispersion, high whiteness and good leveling in the coating production process. In the plastic production process, it has good dispersion, can enhance the strength and hardness of the plastic, maintain the surface gloss and brightness of the plastic, and can also improve the toughness and wear resistance of the product. In high-gloss PP, PE and other high-grade plastic effect is very good.

Main uses: used in various coatings, plastics, rubber, paint, ink, paper, ceramics, batteries, enamel, cosmetics and other fields.

Different applications and specifications of washed kaolin and calcined kaolin


Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.

Barium sulfate is based on barite as the main raw material, through beneficiation, ore washing, crushing and other processes. Barium sulfate has a hardness of 3~3.5 (Mohs) and a specific gravity of 4.3~4.7. It has the characteristics of high specific gravity, low hardness and brittleness. Barite is almost insoluble in water, ethanol and acid, soluble in hot concentrated sulfuric acid. With the development of some high-performance barium sulfate products, the application field of barium sulfate is constantly expanding.
