What Is High Purity Barium Sulfate?
High Purity Barium Sulfate is a white, crystalline inorganic compound (BaSO₄) refined to a purity level exceeding 99%. Unlike standard grades, this form is specifically processed to remove heavy metals and impurities, ensuring a high-performance, non-reactive filler or pigment for specialized industrial processes.
Why Choose Our High Purity Barium Sulfate?
Choosing the right barium sulfate means selecting purity, consistency, and functionality. Here's why industries around the globe choose us:
✅ Ultra High Purity
With a BaSO₄ content ≥ 99.5%, our High Purity Barium Sulfate ensures low impurity levels, meeting the strictest standards in coatings, medical, and high-tech sectors.
✅ Brilliant Whiteness
Superior whiteness and light reflectivity make it an ideal pigment extender in high-end paints, plastics, and films.
