1 insoluble in water and acid, stable chemical properties, no magnetic toxicity, and there is absorption of X - ray and gamma - ray properties. Barite is mainly produced in the deposition of layered deposits and low temperature hydrothermal veins, often associated with quartz, dolomite, calcite, fluorite, galena, sphalerite, chalcopyrite etc..
2 is mainly used in oil and natural gas drilling mud weighting agent, is also the extraction of metal barium and the preparation of a variety of barium compounds, an important mineral raw materials. The most important industrial barium compounds of barium carbonate, barium chloride, barium sulfate, barium nitrate, barium hydroxide, barium oxide, barium oxide, barium chromate, barium molybdate, barium chlorate, lithopone, Solbar etc.. The use of barium compounds is very wide: used in rubber, plastic, paint, paint, paper, textiles, paints, inks, electrode materials and used as filler; barium grease, oil refining, sugar beet, artificial silk raw materials; used as insecticide, germicide, rodenticide, explosives, fireworks, flares, green X light flares, medical camera indicator; also used in glass, ceramics, leather, electronics, building materials, metallurgy and other departments. As a metal barium getter, bonding agent and vacuum tube tv. Alloys made of barium and aluminum, magnesium, lead, silver and other metals are used in the manufacture of bearings.
3 printing and dyeing mordants, fabric sizing agents, increasing agent, papermaking filler, fireproof fabric and leather filler, laxatives and production stomach medicine three magnesium silicate pharmaceutical raw materials, esophageal, gastrointestinal X-ray angiography in the diagnosis of X in the production of yeast, monosodium glutamate and toothpaste with stabilizer of calcium hydrogen phosphate also, for the preparation of plant hibernation extender. For preparation of plating solution crack in metal plating, conductive salt in nickel plating solution, can make the coating soft flour.
4 used as adhesives, sealants, rubber, plastics, paint, ink, white paint, insulation with the filler for rubber and plastic products, can be given by X ray impermeable, and can improve the flame resistance of chloroprene rubber. Textile can be used as sizing agent. The production of printing paper and coated paper as a surface coating agent. The electroplating industry is used as the conductive salt of the nickel plating solution, which can improve the dispersion of the electroplating solution. Used as a clarifying agent in glass manufacturing, with increased gloss and. Is also the manufacture of enamel, ceramics, pigments and other barium salts and other raw materials and X - ray X-ray gastrointestinal contrast agent, etc..
