Hot Sale High Quality Low Price White Barite 4.2 API grade
Barite is chemically stable, insoluble in water , without magnetism and toxicity. The chemical composition of the barite is BaSO4, and the crystal belongs to the sulfate mineral of the orthonormal (trapezoid) system. It is usually thick plate or columnar crystals, which are mostly dense or lumpy or plate like and granular aggregates. Pure colorless transparent, impurities are dyed various colors, white streak, vitreous luster, transparent to translucent.
Barite is a barium sulfate (BaSO4) as the main ingredients of non-metallic minerals, pure barite show white, shiny, because of the influence of impurities and foreign matter are often gray, light red, light yellow, crystalline quite good barite can also appear transparent crystal. Barite is a mixture.
Produce barium sulfate by processing and purifying barite. It is almost insoluble in water, ethanol and acid.It is dissolved in the concentrated sulfuric acid.
Barium Sulfate BaSO4 Typical properties:
1. Resistant to acids and alkalis.
2. Insoluble in water and organic solvents
3. An inert product which is lightfast and weatherresistant
4. Colourneutral, due to its low refractive index
5. Extremely narrow particlesize range for high gloss specifications
6. Extremely good wettability due to low specific surface area
7. Low abrasion during processing, due to low Mohs hardness
