At room temperature, monoclinic ZrO 2 transforms to a tetragonal phase (tII) which is related to the high-temperature tetragonal structure (tI). For example, to find all systems containing zirconium oxide, enter ZrO2, or Zr-O. Introduction. Naturally occurring zirconium is composed of five isotopes.
