Zirconium dioxide (ZrO. 2), sometimes known as zirconia (not to be confused with zircon), is a white crystalline oxide of zirconium. 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 colours for use as a gemstone and a diamond simulant. 1 Production, chemical properties, occurrence.
Description: Named for the gemstone in which it was first discovered (which itself is named from the Arabic word meaning gold color), zirconium is a hard, lustrous, gray-white metal. It is common in very cool stars and has been found in the Sun and in meteorites. Zirconium seems to be common in Moon rocks. It is resists water, most acids and bases, so much so that it is used as a shield against corrosive compounds in the chemical industry. It will react with air under certain circumstances.
