Precipitated barium sulfate does not change color when encountering hydrogen sulfide

Release time:


There are two types of barium sulfate, one is precipitated and the other is water washed, producing barite. Industrial products include crushed barite and precipitated barium sulfate made from barite through chemical reactions.

Barium sulfate dissolves in acid alkali metal salts and becomes barium carbonate, which is slightly soluble in concentrated sulfuric acid and insoluble in other acids and bases.

Although precipitated barium sulfate has the same chemical properties as barite powder, it has no crystallization performance and is amorphous, with a very soft texture. Its oil absorption and covering power are higher than those of barite powder. It is very stable to air and heat, and does not discolor when it comes to hydrogen sulfide and toxic gases.
