Barium Sulfate Precipitated 98% - High Whiteness Filler for Coatings, Plastics & X-Ray Contrast
Barium sulfate (BaSO₄) is a vital barium salt compound manufactured as precipitated barium sulfate through chemical precipitation. This white fine powder offers exceptional physicochemical properties including high chemical stability, superior whiteness, high density (4.5 g/cm³), high refractive index, low hardness, and excellent dispersibility. These characteristics make it an indispensable functional filler and specialty chemical for high-end coatings, plastics and rubber, papermaking, radiation shielding engineering, medical diagnostics, and inks, significantly outperforming standard mineral fillers.
Optical Performance Enhancement for High-End Coatings and Inks
Improved Opacity and Gloss: In coatings (automotive paints, industrial coatings, powder coatings) and inks, precipitated barium sulfate effectively scatters light due to its high refractive index, significantly enhancing hiding power (substrate coverage) while providing excellent surface gloss, fullness, and leveling to the film.
Enhanced Durability: Improves film weatherability, chemical resistance, and scratch resistance, extending coating service life.
High-Performance Functional Filler for Plastics and Rubber
Reinforcement and Weighting: Enhances rigidity, dimensional stability, surface hardness, wear resistance, and heat resistance in engineering plastics (PA, PBT, PP) and rubber products.
Specialized Applications: Used in high-gloss PP, matting masterbatches, flame-retardant materials, and products requiring increased specific gravity (fishing sinkers, counterweights).
Specialized Protection for Medical Diagnostics and Radiation Shielding
X-Ray Contrast Agent: Medical-grade high-purity barium sulfate serves as the standard positive contrast agent for gastrointestinal X-ray/CT examinations, clearly outlining digestive tract morphology for diagnosing ulcers, tumors, and other pathologies.
Radiation Shielding Concrete: Used as heavy aggregate in radiation-shielding (X-ray, gamma-ray) concrete for protective walls in nuclear facilities, hospital radiology departments, and industrial radiography rooms.
Additional Industrial Applications
Paper Manufacturing: Enhances paper whiteness, smoothness, printability, and opacity.
Ceramics and Glazes: Increases whiteness and gloss in high-grade ceramic glazes.
Friction Materials: Adjusts friction coefficient and wear resistance in brake pads and clutch facings.
Solid Lubricant: Serves as auxiliary lubricating material in extreme environments.
Product Grading and Specifications
Our barium sulfate is precisely categorized by application into Coating Grade, Plastic Grade, Paper Grade, Pharmaceutical Grade (USP/ChP compliant), and Radiation Shielding Grade. Key parameters include whiteness, particle size distribution and diameter, residue on 325-mesh sieve, oil absorption, and impurity content (sulfides, iron, lead).
Safety and Compliance Information
A clear distinction exists between Industrial Grade and Pharmaceutical/Food Grade. While barium sulfate itself is insoluble with low toxicity, soluble barium salts (barium chloride) are highly toxic. Pharmaceutical-grade products maintain stringent standards for purity, bacterial endotoxins, heavy metals, and soluble barium salts. Industrial applications present no special toxicity risks, though standard dust protection measures should be observed.
Our precipitated barium sulfate features high whiteness, uniform and controllable particle size distribution, excellent dispersibility, and superior chemical purity. We provide customized solutions for coating and ink manufacturers, plastic and rubber processors, paper mills, medical device companies, and specialty engineering material suppliers. Based on specific requirements for gloss, transparency, specific gravity, or radiation shielding performance, we recommend optimal grades and provide comprehensive technical support.
