Product introduction:The precipitated barium sulfate is white amorphous powder with a relative density of 4.50 (15 degrees) and a melting point of 1580 degrees. Because of its high refractive index (1.63~1.65), it shows a lighter color and has a certain hiding power. It is almost insoluble in water, ethanol and acid, and is soluble in hot sulfuric acid. It is easy to mix with Potassium Permanganate, calcium carbonate or metal nitrate. It can be reduced to barium sulfide with carbon at high temperature. It is an important basic chemical raw material. It is used as the raw material or filling agent for paint, paint, ink, plastic, rubber and battery; the surface coating agent of printed and copper sheet; the sizing agent used in the textile industry; and the clarifying agent in the glass products; it can play the role of defoaming and increasing luster. It can also be used as a protective wall for radiation protection. It is also used in porcelain, enamel and dyestuff industries, as well as raw materials for making other barium salts.
Commodity Description:Appearance and character: white trapezoid crystal. Melting point (c): 1580 degrees centigrade. At 1149 C, it is converted into monoclinic crystallization. It is easy to caking when drying. Relative density: 4.50 (15 C) solubility: insoluble in water and insoluble in acid. The solubility of the water in the water is only 2.448x10g/100g water. A concentrated sulfuric acid dissolved in heat. It is difficult to dissolve in water insoluble in ethanol and dilute acid. Caking when dry. Industrial precipitated barium sulfate itself is not toxic, but if it contains soluble barium compounds, it can cause poisoning.

1, the particle size distribution is narrow, with smaller specific surface area and base dosage, which can obtain high gloss and fluidity.
2, high inert chemical substances, acid and alkali resistant, has good anti sun and weather resistance.
3, high purity, less impurities, no trace minerals and salt impurities (no corrosion or vulcanization).
4, easy to disperse, can improve the strength, wear resistance and geometric stability of products.
It has good compatibility with the matrix and is tightly combined.
1. Barium sulfate is mainly used as weighting agent in drilling fluid for oil and natural gas. It is also an important mineral material for extracting barium and producing various barium compounds.
2, barium sulfate is also used in leather, electronics, building materials, glass, ceramics, metallurgy and other departments.
3. Barium sulfate is used in industries such as pigment, rubber, powder coatings, paint, ink, battery, plastic and copper board.
4. It is used to make surface coating agents for paper and copper paper, textile sizing agent, glass clarifier, ink, plastic, paint, rubber filling agent and so on.
5. Barium sulfate is used as clarifying agent in glass products. It can defoaming and increase luster. It is used in ceramic, enamel, spice and pigment industries.
Packaging and storage: packed in latex or woven bags lined with polyethylene plastic bags.
Stored in a dry storeroom. When making white pigment, it is not allowed to store and mix with colored articles in order to prevent contamination of color.
