  1. 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.

  2. 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.

  3. 15 Απρ 2017 · The structural, mechanical and thermodynamic properties of ZrO 2 polymorphs (namely, monoclinic (P 2 1/c), tetragonal (P 4 2/nmc), cubic (F m 3 ¯ m), and orthorhombic (Pbca and Pnma)) are investigated systematically by employing DFT functionals (LDA, PBE and PW91).
