“…Anion vacancies are an important factor for the extraordinary ionic conductivity of zirconia-based ceramics. Incorporation of nitrogen into the anion sublattice of zirconia is another way to form anion vacancies, first pointed out by Gilles et al [4,5], who investigated the ammonolysis and nitridation of ZrO 2 /ZrN mixtures at temperatures between 900 and 2000 °C. One of the most potential applications of nitrogen doped zirconia is its prospective use as catalytic active material.…”

A thorough comparison between the slowly and fast cooled ß"-type oxynitrides of zirconium has been carried out by means of transmission electron microscopy. This work aims at detecting and analyzing the so-called "modulated" β'' phase, which has been involved in the introduction of ordered anion vacancies through nitridation of zirconia. The gained information from the occurrence of such a modulated phase and the manner, in what it appears, do support the suggested structure model, which had been developed in early works in order to get a better understanding of the typical phase transitions in zirconium oxynitrides.*

“…First studies of the system Zr-N-O were made by Gilles et al [8,9], who investigated the ammonolysis and nitridation of ZrO 2 /ZrN mixtures at temperatures between 900°C and 2000°C. They detected three oxynitride phases (γ, β, β'), which are structurally derived from the fluorite type of cubic zirconia (ordered anion vacancies).…”

Slowly cooled nitrided zirconia samples were investigated and characterized by means of transmission electron microscopy (TEM). Besides the well‐known different modifications of ZrO2 some ZrO2‐rich oxynitride phases could be further found, called β‐type phases. An overview regarding the formation of such different structural modifications could be gained, supported by previously performed measurements using powder X‐ray diffractometry (XRD). Similar to fast cooled nitrided zirconia samples Zr(N,O), the slowly cooled ones also contain different kinds of ZrO2 precipitates, which can be obviously emphasized by using the methods of diffraction contrast. A super cell was successively built, derived from the unit cells of the β and β′ phase, in order to explain the structure of the observed modulated β″ phase. Agreements from the comparisons between experimental high resolution images and the simulated ones of such modulated structures confirm the suggested starting points.
