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 or Zircon Sand. Zircon Ore is mined from natural deposits and concentrated by various techniques.
Zirconium Silicate is used for manufacturing refractory materials for applications where resistance to corrosion by alkali materials is required. It is also used in production of ceramics, enamels, and ceramic glazes. In enamels and glazes it serves as an Opacifier. It can be also present in some cements. Another use of zirconium silicate is as beads for milling and grinding.
Zircon is a very stable, hard, dense, and an excellent refractory material resistant to heat attack and resistant to aggressive environments. Due to this property, it is also used in the manufacturing of moulds for casting molten metals in the Foundry.
