Precipitated barium sulfate
Precipitated barium sulfate is a function filler that is superfine in nature and exhibits a low absorption threshold. It occurs as colorless orthorhombic crystals or a white amorphous powder and does not dissolve in water, ethanol, and acid but is soluble in hot concentrated sulfuric acid.
By barium sulfide solution and to join after remove calcium and magnesium mirabilite solution mixing, reaction at 80 â??, precipitate, after the suction filter, washing and acid pickling, adjust pH value 5 ~ 6, filtration, drying and crushing.It can be prepared with barium yellow halogen and glauber solution.
Precipitated barium sulfate is produced with advanced chemical precipitation method, good physical properties, low mechanical impurity, even fineness; white powder or paste, non-toxic, insoluble in water, soluble in fuming sulphuric acid , stable chemical property; It can absorb X-rays, endow the materials with high density and surface finish. It is used in producing paint, ink, coating, plastic, rubber, chip friction pieces, ceramics, glass, electronics, cosmetics, medicine, food etc.
Description: produce barium sulfate by processing and purifying barite.
Typical properties:
Resistant to acids and alkalis
Insoluble in water and organic solvents
An inert product which is lightfast and weatherresistant
Colourneutral, due to its low refractive index
Extremely narrow particlesize range for high gloss specifications
Extremely good wettability due to low specific surface area
Low abrasion during processing, due to low mohs hardness

Iron oxide red is used as dye or colorant in various prefabricated concrete parts and architectural products and materials. It is directly added into cement to color up various indoor and outdoor cement surfaces, i.E. Walls, terraces, ceilings, pillars, corridors, roads, car-park, stairs, stations, etc, as well as various building ceramic and glazed ceramics, i.E. Facing bricks, floor tiles, roofing tiles, panels, terrazzo, mosaic tiles, artificial marbles, etc.

Process with excellent control of particle-size and unique coating technology. It is coate r915 for coating is rutile titanium dioxide pigments manufactured by the sulphate d with inorganic and special organic surface treatment. It has excellent pigment properties, with good whiteness and gloss, excellent hiding power strong tinting strength, superior weatherability and chalk resistance, is easy wetting and easy to disperse. R915 can endow the coating film bright color, enhance its mechanical strength & adhesion and keep it from crazing. It can also prevent the penetration of uv or moisture, improving the chalk resistance of film to extend its working life.
