Zirconium silicate, with the chemical formula ZrSiO₄, has a theoretical chemical composition of 67.1% ZrO₂ and 32.9% SiO₂, and a molecular weight of 183.3071. It is white or off-white powder, non-toxic and odorless.
Zirconium silicate, with the chemical formula ZrSiO₄, has a theoretical chemical composition of 67.1% ZrO₂ and 32.9% SiO₂, and a molecular weight of 183.3071. It is white or off-white powder, non-toxic and odorless. Zirconium silicate has a high refractive index ranging from 1.93 to 2.01, which makes it potential for application in some optical materials. Its Mohs hardness is 7-8, its specific gravity is 4.6-4.7, its melting point is as high as 2550℃, its decomposition point is 1550℃, and its thermal expansion coefficient is 4.5×10⁻⁶. These properties give zirconium silicate good chemical stability, it is insoluble in water and acid, and it is not easy to react chemically with other substances under normal conditions.
