Zirconium dioxide (ZrO 2), sometimes known as zirconia (not to be confused with zirconium silicate or zircon), is a white crystalline oxide of zirconium. Its most naturally occurring form, with a monoclinic crystalline structure, is the mineral baddeleyite.
27 Οκτ 2021 · The electronic structures and optical properties of the monoclinic ZrO2 (m-ZrO2) are investigated by means of first-principles local d. approxn. (LDA) + U approach. Without on-site Coulomb interactions, the band gap of m-ZrO2 is 3.60 eV, much lower than the exptl. value (5.8 eV).
15 Οκτ 2023 · Because of the interesting properties of zirconia in the segment of ceramics like high optical band gap, low absorption, high melting point, high k-dielectricity, etc., the interest of scientists and researchers in ceramic materials consisting of ZrO 2 nanoparticles is continuously increasing.
