Zirconia Silicate

Zirconia silicate is a deep-processed mineral product derived from natural zircon ore. It appears as a gray-white powder with high Mohs hardness and a melting point above 2500°C. It offers excellent resistance to acids, alkalis, and corrosion, and is not affected by ceramic firing atmospheres.

Product Introduction

Product Features & Applications

The product maintains stable and balanced technical performance, effectively improving ceramic glaze surface hardness and enhancing body–glaze bonding strength. It provides excellent opacity and whitening performance and can partially replace high-cost raw materials such as tin dioxide, offering strong cost advantages.

Our zirconia silicate is widely used in wall and floor tiles, sanitary ceramics, artistic ceramics, glass opacification, enamel glazes, and high-temperature refractory kiln applications.
