Barium Sulfate - BaSO4

What is Barium Sulfate (BaSO4)?

BaSO4 is an inorganic compound with the chemical name Barium Sulfate. It is composed of a barium cation and the sulfate anion. The sulfur is attached to four oxygen atoms. BaSO4 is a sulfate salt of barium and is found as mineral barite. It is a crystalline solid white in color which is insoluble in water and alcohol but soluble in concentrated acids. It is odorless. Barium Sulfate is an alkaline, divalent metal. It is non-toxic and is safe for medical use. It is widely used in the production of oil and natural gas to get high-density drilling fluids by keeping the boreholes free of rock.
