Precipitated barium sulfate is deposited and is one of the few stable salts among sulfates. It is primarily used as a weighting agent in oil and gas drilling muds and is also an important mineral raw material for extracting metallic barium and producing various barium compounds.

Natural barium sulfate, also known as barite, contains impurities such as CaCO3. It can be tested with dilute HCl or dilute HNO3. Natural BaSO4 is used in the production of paints or high-grade paper, and can serve as a white pigment [zinc barium white (ZnS·BaSO4), ZnSO4 + BaS = ZnS·BaSO4] and as a raw material and filler for paint, ink, plastics, and rubber. In the chemical industry, it is used to produce BaCl2 and other barium compounds.

Precipitated barium sulfate is relatively pure and is primarily used in medicine as an oral agent for gastrointestinal examination, specifically in barium meal X-rays.

Precipitated barium sulfate is deposited and is one of the few stable salts among sulfates. It is mainly used as a weighting agent in oil and gas drilling muds and is an important mineral raw material for extracting metallic barium and producing various barium compounds. The most important industrial barium compounds include barium carbonate, barium chloride, barium sulfate, barium nitrate, barium hydroxide, barium oxide, barium peroxide, barium chromate, barium manganate, barium chlorate, zinc barium white, barium polysulfide, and others. Barium compounds have a wide range of uses: they are used as raw materials and fillers in rubber, plastics, pigments, paints, paper, textiles, inks, and welding rods; as barium-based lubricants, oil refining agents, beet sugar refining agents, and artificial silk raw materials; as insecticides, bactericides, rodenticides, explosives, green fireworks, signal flares, tracer bullets, and medical X-ray indicators; and in glass, ceramics, leather, electronics, building materials, metallurgy, and other sectors.
