Also known as barium white, it is a white crystalline solid with the chemical formula BaSO4, which is almost insoluble in water and other traditional solvents. The main component of barite is sulfur, which is a common barium ore. It is a common laboratory and industrial chemical. Insoluble in water and acid, chemically stable, without magnetic toxicity, and has the ability to absorb X-rays and gamma rays. Barite is mainly produced in sedimentary layered deposits and low-temperature hydrothermal veins, often coexisting with quartz, dolomite, calcite, fluorite, galena, sphalerite, chalcopyrite, etc. Mainly used as a weighting agent for oil and gas drilling mud, it is also an important mineral raw material for extracting metallic barium and producing various barium compounds. The most important barium compounds in industry include barium chloride, barium hydroxide, barium oxide, barium peroxide, barium chromate, barium manganese oxide
