Zirconium Silicate (Zr(SiO4)) is a cost-effective and high-quality opacifying agent with a high refractive index of 1.93-2.01 and excellent chemical stability. It is widely used in the production of building ceramics, sanitary ceramics, daily ceramics, and high-end handicraft ceramics, as well as in ceramic glaze processing and production. Due to its chemical stability, zirconium silicate is not affected by ceramic firing atmosphere and significantly improves the bonding properties and hardness of ceramic glaze. It has also found applications in the production of color picture tubes in the television industry, emulsified glass, and enamel glaze in the glass industry. Zirconium silicate has a high melting point of 2500 degrees Celsius, making it suitable for use in refractory materials, glass kiln zirconium ramming materials, castable, and spray coatings.

Zirconium Silicate Powder

  1. Characteristics:

(1) zirconium silicate as a ceramic glaze additive, within a certain particle size range with particle size reduction whiteness, strength, wear resistance, hydrolysis resistance, corrosion resistance are improved, self-cleaning ability enhanced, reduced dosage.

(2)  Because of its strong hydrolysis resistance, zirconium silicate powder can be used as the carrier of nano functional powder in water environment.

(3) Zirconium silicate can be used as surface coating agent for functional powders due to its strong oxidation resistance. For example, the red glaze of Chinese red ceramics is made of nano-zirconium silicate coating agent, red and bright color, do not fade.

(4) Because of the high strength and good wear resistance of zirconium silicate, nanometer zirconium silicate powder is a high quality abrasive medium and engineering ceramic raw material.
