Natural Barium Sulphate | Pigment White 21 | COLORCOM BISUL BS-916 | 7727-43-7, 13462-86-7 | Barium Sulfate

Short Description:

Natural barium sulfate is the raw barite ore, processed by beneficiation, washing, crushing and other processes. It is often in the form of thick plate or columnar crystals, mostly in the form of dense blocks or plates and granular aggregates. Colorless and transparent when pure, stained with various colors when containing impurities, streak white, glassy luster, transparent to translucent.

Natural barium sulfate has a specific gravity of 4.0-4.5, moderate hardness, brittle, chemically stable, insoluble in water, ethanol and hydrochloric acid. It is chemically stable, insoluble in water, ethanol and hydrochloric acid. It is resistant to acid and alkali and water. Barite chemical composition for BaSO4, crystal is orthorhombic (rhombohedral) crystal system of sulfate minerals.

Production technology of Natural Barium Sulphate:

The series of Natural barium sulfate appears to superfine white powder which is made from selected barite ones and deal with elaborate grinding process.


  1. 1.The particle size distribute according to specific proportion, it cause diffuse reflection for film, and form low glossiness coating.
    2.This product has good control ability on particle size top cut, it can coat 35μm film.
    3.Low oil absorption, it makes good flow for coating.

1.Suitable for low glossiness (less than 70 degree) flat and textured powder coating, water-base and oil-base.
2.Suitable for plastic and rubber extender.
3.Suitable for A/B epoxy resin adhesive and various kinds of adhesive filling.
4.Suitable for friction plate, glass, copper casting areas.
5.Others.

Packing: 25kg/Bag.
