What is the use of precipitated barium sulphate?
Precipitated barium sulfate, also known as blanc fixe, is a white crystalline solid with various applications across different industries due to its unique properties. Here are some of its primary uses:
Paints and Coatings: Precipitated barium sulfate is widely used as a pigment and filler in paints, coatings, and varnishes. Its high density, brightness, and inertness enhance the opacity, whiteness, and smoothness of the coatings. It also improves the resistance to weathering and chemical degradation.
Plastics and Polymers: In the plastics industry, barium sulfate serves as a filler to improve the strength, stiffness, and impact resistance of plastic products. It also enhances the brightness and surface gloss of the finished products. It's commonly used in high-gloss, thermoplastics, and thermoset plastics.
Rubber: In rubber manufacturing, precipitated barium sulfate is used as a filler to increase the rubber's weight and improve its resistance to acid and alkali attacks. It also aids in enhancing the mechanical properties and smoothness of the rubber.
Paper: Barium sulfate is used in the paper industry to improve the whiteness, opacity, and gloss of paper products. It helps achieve a high-quality finish and smooth surface on specialty papers and photographic paper.
Cosmetics: Due to its inert nature and fine particle size, precipitated barium sulfate is used in cosmetics and personal care products, such as powders and foundations, to provide a smooth texture, better coverage, and a matte finish without causing skin irritation.
Pharmaceuticals: In the medical field, barium sulfate is used as a radiopaque agent for X-ray imaging and other diagnostic procedures. It helps to provide clear images of the gastrointestinal tract by absorbing X-rays and making the structures more visible.
Radiation Shielding: Given its high density, barium sulfate is also used in certain applications requiring radiation shielding, such as in protective coatings and materials to block X-ray and gamma-ray radiation.
Industrial Applications: Precipitated barium sulfate is used in various other industrial applications, including as a component in ceramics, glass, and brake linings, where it enhances the properties and performance of the final products.
Overall, precipitated barium sulfate is valued for its high purity, fine particle size, chemical inertness, and ability to enhance the physical and aesthetic properties of products in multiple industries.
