摘要：

The phase compositions of undoped and europium-doped zirconia samples, obtained by precipitation and thermal treatment from 350-degrees to 1000-degrees-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.
