【摘要】 以金属盐溶液为原料，采用喷雾热分解法制备了Ｙ２Ｏ３－ＺｒＯ２（ＹＳＺ）超细粉末。利用ＸＲＤ、ＴＥＭ、ＢＥＴ以及激光粒度仪等技术测定了其相组成、结构、比表面积、粒径以及粒径分布。研究了工艺条件对ＹＳＺ粉末性能的影响。更多还原

【Abstract】 Y 2O 3-ZrO 2(YSZ) ultrafine powders were prepared from the water solution of metal salts by spray pyrolysis. By means of XRD,TEM, BET and LS particle size analyser, the YSZ powder charactistics such as powder crystallinity, the specific surface area, particle size and its distribution were examined. The effect of spray pyrolysis process parameters on the properties of as-prepared powders was also studied.更多还原
