  1. Zirconium dioxide - Wikipedia

    • Zirconium dioxide (ZrO 2), sometimes known as zirconia (not to be confused with zirconium silicate or 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 gems… See more

    Production, chemical properties, occurrence

    Zirconia is produced by calcining zirconium compounds, exploiting its high thermostability.
    Three phases are known: monoclinic below 1170 °C, tetragonal between 1170 °C and 2370 °C, a… See more

    Engineering properties

    Zirconium dioxide is one of the most studied ceramic materials. ZrO2 adopts a monoclinic crystal structure at room temperature and transitions to tetragonal and cubic at higher temperatures. The change of v… See more
