> Knowledge > Materials > Barium Sulphate The majority of naturally occurring barium sulphate (BaSO 4) is used in oil and natural gas production. Barium sulphate is used to increase the density of drilling muds and in this way, rocks can move freely and thus prevents the borehole from becoming blocked up.

Barium sulfate Hyperleap

Barium sulfate (or sulphate) is the inorganic compound with the chemical formula BaSO 4. It occurs as the mineral barite, which is the main commercial source of barium and materials prepared from it. The most common naturally occurring minerals of barium are barite (now called baryte ) (barium sulfate, BaSO 4 ) and witherite (barium carbonate, BaCO 3 ), both insoluble in water.

Barium sulphate method for radium-226 analysis by alpha

Barium also forms stable and slightly stronger complexes than radium, and this has been used widely in separating barium and radium via anion exchange. Radium sulphate is the most insoluble of the alkaline earth sulphates, and probably the most insoluble compound of radium known. Barium sulphate is such an excellent carrier for
