Sažetak
The influence of the preparation chemistry on the formation and the stability of metastable t-ZrO2 was studied. gamma-Irradiation has very small (if any) influence on the r-ZrO2 --> m-ZrO2 transition, while increased temperature and pressure caused gradual transition of pure r-ZrO2 to m-ZrO2. Metastable t-ZrO2 containing SO42- impuirties proved to be more stable, and its transition was not uniform. The mentioned effects were monitored by FT-IR and laser Raman spectroscopy. X-ray diffraction was used as a complementary technique.
