Barium sulfate - Wikipedia

Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4.It is a white crystalline solid that is odorless and insoluble in water.It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The white opaque appearance and its high density are exploited in its main applications.

strontium sulfate (WHO 2001). Crude barite is turned into crushed barite which not only has its own industrial uses but also serves, in turn, as the source for the production of other barium compounds. Crushed barite is first converted to barium sulfide by high-temperature, solid-phase reduction with a carbonaceous reducing agent.
