Barium Sulphate (Barite)

Barium Sulphate (Barite) is the sulfate salt of barium that is found as mineral barite naturally.it is an alkaline, divalent metal. Barium sulfate is quite insoluble in water and alcohol. Barium sulfate is a white or yellowish odorless powder that is soluble in hot sulphuric acid. Barium Sulphate (Barite) is a metal sulfate and is safe to use. It is a barium salt that is a radiographic contrast agent in diagnostic x-ray procedures.

Barium Sulphate (Barite) is a fine heavy powder or polymorphous crystal. Its crystalline structure is orthorhombic. It is opaque tasteless powder. It is very soluble in cold water but practically insoluble in dilute acids and alcohol. It is very slightly soluble in alkalis and also in solutions of salts but not soluble in many organic solvents. Its vapor pressure is 00mmHg at room temperature. When heated to decomposition at high temperature it emits toxic fumes of sulfur oxides. Its refractive indices are 1.636 (alpha), 1.637 (beta), and 1.648 (gamma).

It has various applications.

  • It serves as a coating material in the casting of copper anode plates.
  • It is a helpful component in oil well drilling fluids.
  • It works as a filler for plastics to increase the density of the polymer.
  • To test the pH of the soil Barium Sulfate is the best.
  • It acts to modify the consistency in oil paints.
  • It is utilized in imaging the GI tract during barium meals.
  • It can diagnose certain disorders of the intestines or esophagus.
  • It functions in the manufacturing of alloys.
  • It is also used in cosmetics and many personal care products.
  • It is served widely in the production of natural gas.
