We offer barium sulphate which is the white crystalline solid with the formula BaSO4. Barium sulphate is used as Radio contrast agent, Pigment, Pyrotechnics, as filler in plastics and as a component of oil well drilling fluid to increase the density, in brake linings, acoustic foams, powder coatings and in root canal filling. It is also used in manufacturing Lead Acid Batteries.
Barium Sulphate Powder is used as filler in paints for oil well drilling. It is widely demanded in electronic industry for manufacturing lead acid batteries. It is ideal to be used in various manufacturing applications and mixed into heavy concrete to serve as a radiation shield.
