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.


Typical properties:
1.Resistant to acids and alkalis.
2.Insoluble in water and organic solvents
3.An inert product which is lightfast and weather resistant
4.Colour neutral, due to its low refractive index
5.Extremely narrow particle size 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
