Barium Sulfate

Barium Sulfate is a white powdery substance that naturally occurs as mineral barite, which is the main commercial source of barium and other materials prepared from it. Barium Sulphate exhibits complete solubility in concentrated sulphuric acid with sparingly or no solubility in other acids, alcohols and water. Barium Sulfate is odorless.

 

 

All of the major applications of Barium Sulphate are based on its high opaque appearance and high density. Barium Sulfate is used as white pigment for paints and used as filler in plastics. In Oil Paint, Barium Sulphate is almost transparent and is used as filler or to modify consistency. About 80% of the world’s Barium Sulfate is used as a component in Oil Well Drilling Fluid as it increases the density of the fluid. Barium Sulfate is also nowadays being used clinically as a radio contrast agent for X-ray imaging and other diagnostic procedures. Barium Sulphate is also used in the manufacture of other Barium Salts.
