Barium sulfate mineral is called barite. As a white amorphous powder. Stable, insoluble in water, acids, bases or organic solvents. Radiology Barium sulfate is mainly the use of X-rays that can be absorbed in the gastrointestinal tract and the role of developing it, it is mainly used for gastrointestinal contrast agent. For the manufacture of barium salt. Characters: Orthorhombic, mostly plate-like crystals, short column, the general was dense block, plate, columnar output. Colorless crystals, generally white, gray, gray, yellow, pink, light blue, brown and other colors. Glass luster, fracture pearl luster, white streak. as fillers adhesives, sealants, rubber, plastics, paint, ink, white paint, insulation tape, etc., can be given rubber and plastic products to X-ray impermeability and improves chloroprene rubber flame resistance. It can be used as textile sizing agent. Printing paper and coated paper production is used as a surface coating agent. Nickel plating industry as conductive salt solution, plating solution can be improved dispersion. Glass used as a clarifying agent, having increased gloss and defoaming action. Is also the manufacture of enamel, ceramics, pigments

Barium sulfate The mineral is barite barium sulfate. White amorphous powder. Difficult to dissolve in water, acid, alkali or organic solvent. The use of barium sulfate as the main use of barium sulfate in the gastrointestinal tract can absorb X rays and the development of the role, so mainly used as gastrointestinal contrast agent. Used for making barium salts, etc.. By barium sulfate solution with the addition of after removal of calcium and magnesium of Glauber's salt mixed solution, at 80 deg.c reactions were carried out precipitate. After filtration, washing and pickling, adjusting the pH value 5 ~ 6, filtering, drying and crushing. Also available barium yellow brine and mirabilite solution was prepared. Application of barium sulfate Barium sulfate can be used as a paint, ink, plastic, ad paints, cosmetics, battery raw material or filler, rubber products can be used as the filler and reinforcing effect, poly ethylene chloride resin as a filler and weighting agent, printed like paper, copperplate paper surface coating agents, textile sizing agent. Glass products used as a clarifying agent, can play a role in the role of the bubble and increase the luster. Protective wall material capable of being used as radiation protection ray. Also used in ceramics, enamel, spices and pigments and other industries. Manufacturing is also of other barium salts of raw materials -- powder coating, paint, ship paint, ordnance equipment paint, automobile paint, latex paint, interior and exterior architectural coatings, improve product light resistance, weather resistance, chemical and electrochemical corrosion products and decorative effect, coating enhanced the impact strength. The inorganic industry is used as the raw material for the manufacture of other barium salts, such as barium hydroxide, barium carbonate and barium chloride. For primer paint printing and modulation wood industry production of wood printing plate. As a green pigment and filler Lake production in organic synthesis. Printing - ink filler, can play the aging resistance, resistance to exposure, increase adhesion, color clear, bright, non fading effect. Filler, tire rubber, insulation rubber, rubber plate, adhesive tape, engineering plastics can enhance the product anti-aging performance and climate resistance, the product is not easy to aging embrittlement, and can significantly improve the surface finish, reduce production cost, as the main filler for powder coating is the primary means of regulating the powder bulk density increased rate of the powder.
