Engineering properties. Bearing balls. 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.
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.
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).
Key properties that make zirconium dioxide such a versatile compound include its high melting and boiling points, its robustness against chemical attacks, and its excellent mechanical strength and wear resistance.
16 Απρ 2020 · The structural properties of ZrO 2 nanopowder are studied through the X-ray diffractometer (Rigaku, Ultima-IV). The surface morphology and size of nanoparticles is investigated through Field Emission Scanning Electron Microscopy (JEOL,JSM-7100F).
4 Ιουν 2021 · The finding of zirconium compounds in nature, the physical and chemical properties of ZrO2 are given, the polymorphism of zirconium oxide, and the phase diagrams of systems with its...
