Description:
Barium Sulfate is white powder, the relative density is 4.0-4.4, good whiteness, good dispersion,is non-toxic tasteless. Resist acid, alkali and organic solvent. Can not Reaction with any gas. So Barium Sulfate have heat resisting, weather fastness, corrosion resisting property, It is the best choice for many chemical usage.
