Product Description

Zircon Flour Zirconia Powder Zirconium Silicate  for Ceramic Glaze

Product Description

Description of Zirconium Silicate:

High refractive index of 1.93-2.01, chemical stability, is a kind of low-cost opacifier, used in the production of various architectural ceramics, sanitary ceramics, daily-use ceramics, first-class handicraft ceramics, etc., in the production of ceramic glaze In the processing and production, it is used and applied in a large amount.

The reason why zirconium silicate is used in the production of ceramics is also because of its good chemical stability, so it is not affected by the firing atmosphere of the ceramics, and it can improve the bonding properties of the ceramic glaze and the hardness of the ceramic glaze surface. Zirconium silicate has also been further used in the production of color picture tubes in the TV industry, emulsified glass in the glass industry, and enamel glaze production. Zirconium silicate has a high melting point: 2500 degrees Celsius, so it is also used in refractory materials, glass furnace zirconium ramming materials, castables, and spray coatings.

Product Application

Applications of Zirconium Silicate in Ceramic Industry

Zirconium Silicate has different kinds of applications in the ceramic industry, including as a whiteness and opacity booster. It's also used as a raw material in ceramic glazes to promote opacity, as well as in glass compounds to make beautiful, opaque white glazes. It improves erosion and chemical resistance when used in glazes.

Uses of Zirconium Silicate in others

Zirconium Silicate Powder is a high-quality product with a good refractive index of 1.93-2.01. In spite of being used widely in the production of various ceramics, it is also widely used in refractory materials, zirconium ramming materials, casting materials spray coatings and dental crowns.
