Precipitated Barium Sulfate Powder / BaSO4 Powder (BaSO4 Super Grade 99.5% 3um)

Precipitated Barium Sulfate Powder

Precipitated Barium Sulfate powder is a white, crystalline powder that is widely used across various industries due to its chemical stability, insolubility in water, and unique physical properties. It is produced by precipitation reactions, typically through the reaction of barium chloride (BaCl₂) or barium nitrate (Ba(NO₃)₂) with sulfuric acid (H₂SO₄) or sodium sulfate (Na₂SO₄). Precipitated barium sulfate has a high degree of purity, fine particle size, and uniformity, which makes it suitable for a range of industrial, medical, and commercial applications.

Applications

Paints and Coatings:

Pigments and Fillers: Precipitated barium sulfate is widely used as a white pigment and filler in paints, coatings, and inks. Its high opacity, brightness, and chemical inertness make it ideal for improving the whiteness and coverage of coatings. It is particularly useful in high-gloss paints and automotive coatings due to its ability to enhance durability and weather resistance.

Anti-corrosive Coatings: Barium sulfate is often incorporated into anti-corrosive coatings for steel and metal substrates. Its high density and inert nature help to provide a protective barrier against corrosion in harsh environments.

Plastic and Rubber Industry:

Fillers in Plastics and Rubber: BaSO₄ is widely used as a filler material in plastics and rubber. It helps to reduce the cost of products, improve processing characteristics, and enhance the physical properties of the final material, such as stiffness, density, and mechanical strength. It is used in automotive parts, cables, and other molded plastic products.

Improved Mechanical Properties: In rubber, barium sulfate improves the density, durability, and resilience of the material, which is why it is used in rubber seals, gaskets, and tires.

Medical Applications:

Contrast Agent in X-ray Imaging: One of the most prominent uses of precipitated barium sulfate is as a contrast agent in radiology and X-ray imaging. BaSO₄ is insoluble in water, making it an ideal agent for gastrointestinal imaging. When ingested or introduced into the body, it helps to highlight internal structures, such as the stomach, intestines, and esophagus, by absorbing X-rays and providing clear images. It is typically used in barium swallow, barium enema, and barium meal procedures.

Medical Tablets and Capsules: In some formulations, barium sulfate is used as an excipient in tablets and capsules. Its high density helps to provide the required weight and size to medications. It is especially useful in creating contrast agents for imaging and diagnostic purposes.

Oil and Gas Industry:

Drilling Fluids: Precipitated barium sulfate is often used as a weighting agent in drilling fluids for oil and gas exploration. It helps increase the density of the fluid, which is necessary to counterbalance high-pressure formations and prevent blowouts during drilling.

Wellbore Integrity: Barium sulfate is used to improve the integrity of the wellbore by enhancing the stability and performance of the drilling fluids, ensuring that they maintain appropriate pressure and viscosity under various environmental conditions.

Textile Industry:

Textile Printing: Precipitated barium sulfate is used in textile printing as a filler and colorant. It helps to provide opacity to printed designs and improves the coverage of pigments used in textile products.

Dyeing and Finishing: BaSO₄ is used in the dyeing and finishing processes of textiles to improve whiteness, enhance brightness, and provide better finishing to fabrics.
