Zircon (Zirconium Silicate, ZrSiO 4) Zircon is an oxidebased engineering ceramic. It has a moderately high tensile strength and a moderately high density among oxidebased engineering ceramics.
Yttriastabilized zirconia (YSZ) is a ceramic in which the cubic crystal structure of zirconium dioxide is made stable at room temperature by an addition of yttrium oxides are commonly called "zirconia" (Zr O 2) and "yttria" (Y 2 O 3), hence the name.
Zirconium Oxide has high melting point, high electrical resistivity, high refractive index and low thermal expansion coefficient, making it an important high temperature resistant material, ceramic insulating material and ceramic sunscreen.

Because of its low thermal expansion coefficients and high thermal shock resistance, zircon (zirconium silicate) finds widespread use in the ceramic foundry, refractory industries, and as an opacifier in ceramic industry. Zircon is the primary mineral resource for the production of zirconium metal (Zr) and zirconia (ZrO 2).
Quartz: On Mohs scale its hardness is 7, improves SiO2 content and helps in thermal expansion. Zirconium silicate: It is used as an opacifier and induce the brightness. Frits/ powder: It is used as a main flux and helps in fusing the hard materials. Frit is a pre melted glaze.
