Product Description

Product Description

Precipitated barium sulfate is an inorganic compound with the chemical formula BaSO4. It is mainly sourced through chemical synthesis rather than direct mining like natural barite.
The production process begins with barium - containing raw materials, it is first dissolved in water to form a barium ion rich solution. Then, a sulfuric acid based precipitating agent, such as sulfuric acid (H2SO4) or sodium sulfate (Na2SO4), is added. A chemical reaction occurs, where barium ions combine with sulfate ions, resulting in the precipitation of barium sulfate. For barium carbonate, it reacts with sulfuric acid to produce barium sulfate, carbon dioxide, and water.
After precipitation, the resulting barium sulfate particles are separated from the solution, typically through filtration.
Subsequently, the solid is washed to remove impurities and then dried to obtain the final precipitated barium sulfate powder. This synthetic method allows for precise control over the particle size, shape, and purity of the product.

Application

Precipitated barium sulfate, with its unique properties, finds extensive applications. In the paint and coating industry, it serves as an excellent pigment extender, enhancing hiding power and gloss while reducing costs. Its high whiteness and chemical stability make it ideal for producing high quality paints for various surfaces.
In the plastics sector, it acts as a filler, improving mechanical properties like hardness and wear resistance. It also helps in reducing shrinkage during the molding process, ensuring better dimensional stability. For the rubber industry, it enhances the durability and tear resistance of rubber products
