Application: Barium Sulphate It is used as a weighting agent for oil and gas drilling mud, and is also an important mineral raw material for extracting metal barium and preparing various barium compounds. The most important barium compounds in industry are barium carbonate, barium chloride, sulfuric acid, barium nitrate, barium hydroxide, barium oxide, barium peroxide, barium chromate, barium manganate, barium chlorate, zinc barium white, barium polysulfide, etc. Barium compounds are widely used as raw materials and fillers for rubber, plastics, pigments, coatings, papermaking, textiles, paints, inks, welding rods; Used as raw material for barium grease, oil refining, beet sugar making and rayon; Used as an indicator for insecticides, sterilizers, rodenticides, explosives, green fireworks, flares, tracer bullets, medical X-ray images, etc. Also used in glass, ceramics, leather, electronics, building materials, metallurgy and other departments. The metal barium can be used for television and real.
