 Zirconium dioxide (ZrO2), which is also referred to as zirconium oxide or zirconia, is an inorganic metal oxide that is mainly used in ceramic materials. Molar mass 123.218 g/mol, Appearance white powder, Density 5.68 g/cm3, Melting point 2715 °C, Boiling point 4300 °C, Solubility in water negligible
Its great hardness, low reactivity, and high melting point have made it the oldest mineral that can be found on the earth. Zirconium does not occur massively but is bound in minerals, mainly in zircon (ZrSiO4).
Zircon is also known as a precious stone whose color may vary from colorless white to brown, green, etc., depending on the traces of impurities.

Uses:
The main use of zirconia is in the production of ceramics, with other uses including as a protective coating on particles of titanium dioxide pigments, as a refractory material, in insulation, abrasives and enamels. Stabilized zirconia is used in oxygen sensors and fuel cell membranes because it has the ability to allow oxygen 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.

Zirconia is a precursor to the electroceramic lead zirconate titanate ("PZT"), which is a high-K dielectric, which is found in myriad components.

Zirconia is used to make ceramic knives. Because of its hardness, Zirconia based cutlery stays sharp longer than a stainless steel equivalent

Zirconia is also a potential high-k dielectric material with potential applications as an insulator in transistors.

Zirconia is also employed in the deposition of optical coatings; it is a high-index material usable from the near-UV to the mid-IR, due to its low absorption in this spectral region. In such applications, it is typically deposited by PVD.
