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.
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.
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.
1 Νοε 2023 · Because of the special chemical properties of ZrO 2 such as acidic and redox properties and also the ease of preparation and lack of radioactivity, the characterization of pure monoclinic ZrO 2 for isosynthesis has been widely studied.
