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.

Yuanlei Classroom | As a key material, how many applications does precipitated barium sulfate have?


The appearance of precipitated barium sulfate is a white amorphous powder, with a relative density of 4.50 (15 ℃) and a melting point of 1580 ℃. Due to its high refractive index (1.63-1.65), it exhibits a relatively white color and a certain degree of covering power. It is almost insoluble in water, ethanol, and acid, soluble in hot sulfuric acid. It is easy to form mixed crystals with potassium permanganate, calcium carbonate, or metal nitrates, and can be reduced to barium sulfide with carbon at high temperatures.

Wet mica powder is a high-quality mineral filler made from high-quality mica raw materials, which are washed, impurity removed, soaked, crushed, low-temperature dried, and screened. Its unique production process maximizes the preservation of mica's sheet-like structure, large diameter to thickness ratio, high refractive index, high purity, high whiteness, high gloss, low sand and iron content, and other industrial characteristics that cannot be compared to dry process technology. The unique performance of wet mica powder has greatly improved its application in multiple industries such as plastics, paint, rubber, etc., and has a significant effect on improving product performance and reducing costs.

Yuan Lei's Little Knowledge | Application of Wet Mica Powder in Resin and Plastics


Wet mica powder is a high-quality powder with good whiteness, large diameter to thickness ratio, smooth surface, and uniform particle size obtained by special processes of crushing, drying, and grading mica fragments after washing, impurity removal, and purification. It is widely used in rubber, plastics, coatings, paints, cosmetics, and other industries.
