With high refractive index of 1.93-2.01 and chemical stability, it is a high-quality and cheap opacifying agent. It is widely used in the production of various building ceramics, sanitary ceramics, daily ceramics, first-class handicraft ceramics, etc. In ceramics In the processing and production of glazes, it has a wide range of uses and a large amount of applications.

The reason why zirconium silicate is widely used in ceramic production is that it has good chemical stability and is not affected by the ceramic firing atmosphere. It can significantly improve the bonding properties of ceramics and increase the hardness of ceramic glazes.

Zirconium silicate has also been further used in the production of color picture tubes in the television industry, emulsified glass in the glass industry, and enamel glaze production.

Zirconium silicate has a high melting point: 2550 degrees Celsius, so it is also widely used in refractory materials, glass furnace zirconium ramming materials, castables, and spray coatings.

When high-performance zirconium silicate meets the two conditions of whitening and stabilization, it has better properties than zirconium silicate powder, particle morphology, particle size range, dispersion performance in media, and opacification segregation after brick or glaze application. Conventional zirconium silicate.

The whitening effect of zirconium silicate is due to the formation of baddeleyite and so on after the ceramic is fired, thereby scattering the incident light wave. This scattering is generally called large particle scattering or Mie Scattering. Combining theoretical calculations and actual powder production conditions, controlling the d50 value of high-performance zirconium silicate below 1.4um and the d90 below 4.0um will produce the best opacification and whitening effect. In the whitening effect of zirconium silicate, the concentrated particle size range is very important, and it is required to achieve as narrow a distribution of particles as possible during the grinding process of zirconium silicate.
