Product Description
Industrial Grade White Zrsio4 Powder 65% Zirconium Silicate for Ceramics Glaze

Description of Zirconium Silicate:
Zirconium Silicate is a powder that is water insoluble. It is often colorless, although it can also be brown, pale yellow, light red, green, or gray in color. The number 40 is the atomic number. Its melting point is 1540°C and it has a specific gravity of 6.4. ZrSiO4 is a zirconium silicate chemical compound. The molecule has a molecular weight of 183.31. It has a density of 4.56 GM/cm3.
Zirconia silica fume is a compound of zirconium dioxide, zirconium oxide melting products. The production of silicon-zirconium off special device which used to collect the silica powder, not only has the general characteristics of sillca , but also a certain amount of zirconia powder. Zirconia silica has a special use in the field of refractories , injection materials, ceramics and building materials industries and high-strength concrete for its features of low impurities and good activity in refractory.Specifications of Zirconium Silicate

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.
