Zirconium oxide exhibits three well-defined crystal structures, i.e., monoclinic, tetragonal, and cubic (Figure 1) [2]. The monoclinic phase is stable up to 1170°C, and above this temperature it...
ZrO2 crystallizes in the tetragonal P4_2/nmc space group. The structure is three-dimensional. Zr4+ is bonded in a distorted body-centered cubic geometry to eight equivalent O2- atoms. There are four shorter (2.09 Å) and four longer (2.44 Å) Zr–O bond lengths.
ZrO2 is Baddeleyite structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Zr4+ is bonded to seven O2- atoms to form a mixture of distorted corner and edge-sharing ZrO7 pentagonal bipyramids.
This article provides a detailed overview on zirconia. It covers the stabilisation or zirconia to produce optimal properties and details several applications for the material such as blades, seals, valves, pumps, implants, refractories and electronics.
