Superfine barium sulphate
characteristics:
Adopt advanced chemical precipitation process, owns quite good physical advantages, low mechanical admixture, uniform fineness, no qualitative white powder, non-toxicity, insoluble in water, solute in oleum solute, slightly soluble in boiling hydrochloric acid. with stable chemical character, heat with carbon reduction for sulfide barium, not change color even with H2S or poisonous gas in the air. It is perfect quality can absorb X radial and can improve the glossiness and hardness of the product’s surface.
