About:

Zirconium dioxide (ZrO2), sometimes known as zirconia (not to be confused with zircon) and zirconium oxide, is a crystalline metal oxide that has found its way into the ceramics industry. It is characterized by its high thermal resistivity, mechanical resistance, and abrasive properties. Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite. A dopant stabilized cubic structured zirconia, cubic zirconia, is synthesized in various colors for use as a gemstone and a diamond simulant.
The main use of zirconia is in the production of hard ceramics, such as in dentistry, with other uses including as a protective coating on particles of titanium dioxide pigments, as a refractory material, in insulation, abrasives, and enamels. One of its most popular forms is cubic zirconia, a cubic crystalline compound that is colorless and mechanically tough. Because of its optically flawless property, it serves as a low-cost alternative to diamonds in the jewelry industry.
Zirconium dioxide should not be confused with zircon (or zirconium silicate), a mineral that is also used in the ceramics industry and refractories.
