Barium Sulfate


Barium Sulfate (BaSO₄) is a chemically precipitated, high-purity compound widely used as a filler and functional additive in paints, coatings, pigments, plastics, and lead-acid batteries. Renowned for its outstanding chemical purity and narrow particle size distribution, Barium Sulfate offers excellent dispersion properties, high gloss, and low binder demand. Its extremely low chloride content and reduced electrical conductivity (100 µS/cm) make it ideal for demanding industrial applications. With an average particle size of 1.7 µm and an oil index of 13 g/100g, Barium Sulfate ensures optimal performance in various formulations. It is resistant to water, acids, alkalis, organic solvents, light, and industrial waste gases, including sulfur dioxide. Its versatility and exceptional properties make it a preferred choice for manufacturers in paints, coatings, plastics, and batteries.
