The product is highly effective in absorbing X-rays and γ-rays, endowing materials with high density and surface smoothness. It is widely applied in industries such as paints, inks, coatings, plastics, rubber, ceramics, glass, electronics, cosmetics, pharmaceuticals, and food.

Superfine Barium Sulfate
Superfine Barium Sulfate (BaSO₄) is produced using advanced domestic and international production techniques. The product undergoes ultra-fine processing through purely physical and chemical methods on carefully selected barite (heavy spar). This results in a strict control of particle size, ensuring excellent physical properties. The advanced drying technology used enhances the product's performance, offering better dispersion and affinity with other media during use. The high whiteness and purity of the product, with no mechanical impurities, make it ideal for various industrial applications.
