Baizheng company own two barite mines, which attribute deposit of high-grade pure crystal, its ore natural whiteness up to 92%, the content of BaSO4 is up to 96-99%,the density of more than 4.3, Other heavy metal impurity is very low. We can provide you with 325-5000 mesh Super-fine barium sulfate, as well ground calcium carbonate, hematite and limonite. BaiZheng Super-fine barium sulfate is produced with advanced production techniques, processed with phiscal and chemical means, selected barite to superfine processing, the physical properties of the special superior products has good whiteness and high purity. And narrow & uniform size distribution. In the process of application with other media have good dispersivity and affinity. The outstanding features as following: * Very low oil absorption * Excellent compatibility with coloured pigments * Very high dispersibility * Good filling Capacity * High Gloss in Enamel applications * Imparts impermeability and durability Field of application: Barite can absorb χ-ray, γ-ray and endow the materials with high density and surface finish. As a basic raw material, it is widely application in: * Polymers * Paints * Drilling mud * Construction chemicals * Rubbers * Plastics * Glass. specification high-class products First grade quality products BaSO4 % 99.0 98.0 96.0 Whiteness % 95 92-96 90-92 105°C volatile matter% 0.30 0.30 0.50 Water solvable material% 0.15 0.15 0.30 Moisture % 0.15 0.15 0.50 Fe % 0.04 0.05 0.05 Density g/cm3 4.3-4.6 Oil Absorption g/100g 9-13 PH 7-10
