Application of zirconium silicate powder

Widely used in ceramics, wall and floor tiles, glazes, glass, electronics, and other fields. The particle size is fine, the distribution is reasonable, the whiteness is high, the hiding power is strong, and it can significantly improve the ceramic body-glaze bonding performance, increase the hardness of the ceramic glaze surface, and replace expensive tin dioxide and zirconium dioxide. It has strong wear resistance and a whitening effect.
