摘要

氧化锆的稳定机理有几个有争议的观点。采用水热法制备了纯氧化锆和5%mol Y2O3掺杂氧化锆粉体。用XRD对纳米晶的结构进行了表征,用TEM对氧化锆纳米晶的尺寸进行了观察。结果表明,纯氧化锆和掺杂氧化锆的尺寸分别在30nm以上和30nm以下。同时对298K ~ 1073K范围内的样品进行XRD分析,观察尺寸随相变的变化。

The study of Y2O3-doping-induced size diversification of ZrO2 nanocrystals
The stabilization mechanism of the zirconia has several controversial opinions. With the method of hydrothermal, pure zirconia and 5%mol Y2O3 doped zirconia powders are prepared. XRD is used to exam the structure of the nanocrystals and TEM is used to observe the size of zirconia nanocrystals. It is shown that the size of pure zirconia and doped zirconia is above 30nm and below 30nm, respectively. The examples are also analyzed with the XRD from 298K to 1073K simultaneously to observe the variation of the size with the phase transformation.
