Zirconium Silicate Powder

Zirconium silicate powder is a versatile material with a wide range of applications. It is a hard, wear-resistant material that is also resistant to heat and corrosion. Zirconium silicate powder is an important material in a variety of industries.

Introduction of zirconium silicate powder

Zirconium silicate is a non-toxic, odorless white or off-white powder with a molecular formula of ZrSiO4 and a theoretical composition of 67.2% ZrO2 and 32.8% SiO2. The refractive index is 1.93-2.01, the Mohs hardness is 7-8, the thermal expansion coefficient is 4.2×10-6, the true specific gravity is 4.68-4.71, the melting point is 2500°C, and the decomposition point is 1550°C.

Application of zirconium silicate powder

Widely used in ceramics, wall and floor tiles, glazes, گلاس, 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.
