Zirconium silicate, also zirconium orthosilicate, (ZrSiO4) is a chemical compound, a silicate of zirconium. It occurs in nature as the zircon, a silicate mineral. Zirconium silicate is also sometimes known as zircon flour.
Zirconium silicate is usually colorless, but impurities induce various colorations. It is insoluble in water, acids, alkali and aqua regia. Hardness is 7.5 on the Mohs scale.

Usage
Chemical stability, is a high-quality, inexpensive emulsion, is widely used in a variety of building ceramics, sanitary ceramics, daily ceramics, a class of crafts ceramics and other production, in the processing of ceramic glaze production, a wide range of use, large application. The reason why zirconium silicate is widely used in ceramic production is also because of its good chemical stability, which is not affected by the firing atmosphere of ceramics, and can significantly improve the bonding performance of ceramics and improve the hardness of ceramic glaze. Zirconium silicate has also been further applied in the production of color picture tubes in the television industry, emulsified glass in the glass industry, and enamel glaze. Zirconium silicate has a high melting point of 2500 degrees Celsius, so it is also widely used in refractories, glass kiln zirconium ramming materials, castables, and spray coatings.
