Main applications:architectural ceramics, emulsified glass, enamel glaze.

Zirconium silicate powder, with stable chemical properties, is a high-quality and inexpensive opacifier, which is widely used in the production of various building ceramics, sanitary ceramics, household ceramics, first-class handicraft ceramics, etc. It is widely used in the processing and production of ceramic glaze. Zirconium silicate has good chemical stability, so it is not affected by ceramic firing atmosphere, and can significantly improve the body glaze bonding property of ceramics, and improve the hardness of ceramic glaze.

Zirconium silicate also has the following main uses:

1.Can be used in TV industry to manufacture color picture tubes

2.Glass industry manufactures emulsified glass

3.Production of enamel glaze

4.Refractory materials, zirconium ramming materials for glass furnaces, castables, spraying coatings, etc
