Barite powder, also known as barium sulfate powder, its chemical composition is BaSO4. The crystal is classified as orthogonal (oblique) sulfate mineral. Usually its crystal appears to be thick plate or column,and mostly Barite shows as aggregates of dense block, plate or granule. The pure quality is colorless and transparent, and the mineral with impurities is dyed various colors with races of white, shiny, transparent and translucent. Mohs hardness is, and specific gravity is around 4.5g/cm3.
Our Barite Powder (Barium Sulphate Powder) is super-fine powder made from high quality barite ore. After well selection and thoroughly grinding, the end products have good dispersibility, high whiteness, nice covering power, stable chemical properties. When it been used as filler in coating or paint, can adjust coating or paint’s thickness, color and luster and improve chemical stability. When it been used in plastic, can make plastic more durable. And it also been widely used in rubber, paper-making ,ceramics and other industrial fields.
Application
Barite powder is mainly used in and for the following industrial fields:
- As a weighting agent for drilling fluids in oil and gas exploration, with function of cooling drilling head, reinforcing well walls and controlling oil or gas pressure thus to stablize the production and prevent blowout.
- Used to fill in coatings and paints as alternative to higher prices of raw material such as precipitated barium sulfate, lithopone, titanium dioxide and activated silica, with adapatbility to control the viscosity of paint and to make final product colorful shinning and well stable..
- Used as filler in ABS plastics to make product bright and shinning with good ability of strength, stiffness and abrasion.
- Used for the rubber industry. Barite powder with 500 mesh minus can be applied extensively for rubber as a filler, able to reduce costs and improve hardness, acid resistance and water resistance, etc., and it has good reinforcing effect for natural rubber and synthetic rubber.
- Used in paper industry. Barite powder with high fineness can be applied to be filler or coating filler for white paper and copperplate paper in order to enhance whiteness and improve surface coverage.
