Precipitated Barium Sulphate is the non-qualitative white dust or ointment made by chemic sedimentation method that is national and advanced, which has an advantage in physical capability, less mechanical impurity and symmetrical granularity. And it is nontoxic, dissolving in water and boiling HCL but not thick H2SO4. Discoloration in the atmosphere during contacting with H2S or poisonous gas, BaSO4 holds the firm and steady chemic character, which heats up with C together and deoxidize BaS. It is the upper product that compares with the same kinds in quality in the state. It could absorb X-radial and γ-radial and endow material with high density and the luster of surface.
