The zirconium oxide (ZrO2), sometimes known as zirconia (not to be confused with zircon), is a white crystalline oxide of zirconium. Zirconia is produced by calcining zirconium compounds, exploiting its high thermal stability. Zirconium dioxide is one of the most studied ceramic materials. ZrO2 adopts a monoclining crystal structure at room temperature and transitions to tetragonal and cubic at higher temperatures. The main use of zirconia is in the production of ceramics, with other uses including as a protective coating on particles of titanium oxide pigments, as a refractory material, in insulation, abrasives and enamels. Stabilized zirconia is used in oxygen sendsors and fuel cell membranes because it has the ability to allow oxigen ions to move freely through the crystal structure at high temperatures. This high ionic conductivity (and a low electronic conductivity) makes it one of the most useful electroceramics. Zirconium dioxide is also used as the solid electrolyte in electrochromic devices.
The very low thermal conductivity in the cubic phase of zirconia has allowed its use also as a thermal barrier coating, in jet engines and in diesel engines.It is a very common material used in dentistry for the fabrication of dental restorations, in orthopedics are used in the realization of joint components such as the hip and the knee; because of its hardness can be employed to make ceramic knives; also it has potential applications as an insulator in the transistor.
It is also used in the deposition of optical coatings.
