15 Οκτ 2023 · These modern problems need modern solutions, which are possible only by using high-strength materials that are corrosion-resistant and have better wear and tear resistance. Metal oxide nanoparticles fit well for this purpose; in this section, we review only the properties of ZrO 2 nanoparticles.
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).
4 Ιουν 2021 · A review of zirconium dioxide or zirconia ZrO2 is presented. The finding of zirconium compounds in nature, the physical and chemical properties of ZrO2 are given, the polymorphism of...
16 Απρ 2020 · The effect of calcination temperature on structural and optical properties of ZrO 2 nanoparticles is investigated through XRD, FESEM, EDX, FTIR, UV–Vis absorption, fluorescence emission and life time measurements. XRD spectrum reveals the tetragonal phase at calcination temperature 600 °C and crystallinity of samples increases with ...
1 Νοε 2023 · The purpose of this paper is to provide a detailed review of the methods for the synthesis of nano-ZrO 2. Firstly, the basic concept of every synthesis route is introduced. Secondly, different morphologies and crystallite structures of nano-ZrO 2 from every synthesis route are discussed thoroughly.
7 Νοε 2019 · In this study, we developed ZrO2-based bifunctional heterogeneous catalysts for simultaneous esterification and transesterification of microalgae to biodiesel.
22 Ιουν 2018 · Addition of zirconia (ZrO2) to nuclear waste glasses, even in small amount, significantly affects physical properties such as chemical durability, density, viscosity, and glass transition...
