Abstract
Annealing of ZrO2 in a nitrogen atmosphere leads to a nitrogen containing phase called beta '' phase having a trigonally distorted fluorite structure with ordered anion vacancies. DTA/TG investigations indicated that the beta '' phase decomposes into m-ZrO2 above 500 degrees C releasing nitrogen during the reaction with oxygen. Prevention of oxygen uptake by use of closed tantalum tubes instead of open platinum crucibles enabled the detection of a new reversible phase transition at similar to 965 degrees C. The thermoanalytical results have been confirmed by high temperature-X-ray investigation.
