About Barium Sulfate
Barium sulfate is an inorganic chemical compound with the formula BaSO4 and CAS number 7727-43-7. It has a white crystalline solid appearance, is odorless and insoluble in water. Barium sulfate has a melting point of 1580 degree Celsius and boiling point of 1600 degree Celsius.
Barium Sulfate Production
Most of the barium used commercially is obtained from barite. Barite is highly impure; it is processed by carbothermal reaction giving out barium sulfide. To produce barium sulfate of high purity the sulfide or barium chloride is treated with sulfuric acid or sulfate salts.
In laboratories, barium sulfate is produced by mixing barium ions and sulfate salts solutions.
Barium Sulfate Applications
-
About 80 percent of the barium sulfate produced is used as a component of oil well drilling fluid, as it increases fluid density, increasing hydrostatic pressure and reduce the blowout chances in the well.
-
Medical industry buys barium sulfate as it is used as a radiocontrast agent for X-ray imaging and other diagnostic processes.
-
It is used as a white pigment in paints and as a filler in oil paints.
-
In photography, barium sulfate is used as a coating for photographic papers and is used to brighten papers intended for printing.
-
It is generally used as a filler for plastics, increasing polymer density.
-
Barium sulfate is used as catalyst support, in green pyrotechnic formulas and in soil testing.
-
In the copper industry, it is used as a coating substance in casting anode plates of copper.
