## Description

- description: Yttria-doped zirconia has been shown to undergo nitridation in air
    by flash sintering using direct current (DC) electric fields, resulting in the
    formation of zirconium oxynitride, Zr(N,O). This study performed the microstructure
    analysis primarily using scanning transmission electron microscopy for 8 mol%Y2O3-ZrO2
    (8YSZ) nitrided by isothermal flash sintering protocol under DC electric fields
    in air. The findings confirmed the existence of a threshold current density for
    Zr(N,O) formation. The nitrided 8YSZ grains comprised crystal-oriented Zr(N,O)
    fine ellipsoid-shaped grains with 10 – 20 nm in size. The formation of this structure
    is attributed to the nucleation manner of the Zr(N,O) grains to align their {001}
    planes to those of the original 8YSZ grains. The transformation of 8YSZ into Zr(N,O)
    during nitridation could be considered to precede by a replacement of their anions
    from oxygen to nitrogen while maintaining the cation framework of the respective
    crystal structures, as predicted by Bechteler et al.
