Abstrakt

The phase compositions of undoped and europium‐doped zirconia samples, obtained by precipitation and thermal treatment from 350° to 1000°C, have been investigated by powder X‐ray diffractometry, infrared spectroscopy, and cathodoluminescence spectroscopy. The low‐temperature stabilization of tetragonal zirconia is mainly controlled by the presence of anion additives, such as ammonium chloride. The influence of the crystallite size is less important. Cathodoluminescence spectra show a structural similarity between tetragonal and amorphous zirconia.
