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.
Isotopes: Zirconium has 25 isotopes whose half-lives are known, with mass numbers 81 to 105. Naturally occurring zirconium is a mixture of five isotopes and they are found in the percentages shown: 90 Zr (51.5%), 91 Zr (11.2%), 92 Zr (17.1%), 94 Zr (17.4%) and 96 Zr (2.8%). The most naturally abundant is 90 Zr at 51.5%.
