APPLICATION

Barium sulfate is mainly used as a weighting agent for oil and gas drilling mud, and 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 carbonate, barium chloride, sulfate, barium nitrate, barium hydroxide, barium oxide, barium peroxide, barium chromate, barium manganese oxide, barium chlorate, lithopone white, and barium polysulfide.

Barium compounds have a wide range of uses: barium sulfate can be used as a raw material and filler for rubber, plastics, pigments, coatings, papermaking, textiles, oil and chemical paints, inks, and welding rods; Used as a raw material for barium based lubricating grease, oil refining, sugar beet production, and artificial silk; Used as an indicator for insecticides, sterilizers, rodenticides, explosives, green fireworks, signal flares, tracer flares, medical X-ray imaging, etc; It is also used in sectors such as glass, ceramics, leather, electronics, building materials, metallurgy, etc. Barium metal can be used as a suction and bonding agent for televisions and vacuum tubes. Barium is an alloy made with metals such as aluminum, magnesium, lead, and silver for the manufacture of bearings.
