Barium sulphate powder

 

Using advance synthesis technology of domestic, our quality control system for our superfine BaSO4 is much sticker than that of the oversea market. We firmly control the size of our products, thus it has quite high dispersity and affinity with the other mediums in using.

Our superfine BaSO4 has quite high purity, whiteness, low Fe, no mechanical admixture. It can absorb X radial, γ radial, also can improve the glossiness and hardness of the product’s surface.

 

Precipitation BaSO4 is produced by advanced chemical precipitation technology, it has the character of quite good physical advantages, low mechanical admixture, uniform fineness, non-toxicity, dispersible in water, can solute in oleum, solute quite a little in boiling hydrochloric acid.

Our precipitation BaSO4 has quite stable chemical character, will not change color even with H2S or poisonous gas in the air, It can absorb X radial, and can improve the glossiness and hardness of the product’s surface.
