本研究采用了一种新颖的粉体制备方法-醇-水溶液加热法来制备纳米ZrO_2(Y_2O_3)粉体.实验结果表明:通过选择适当的条件,该方法可制得粒径小、团聚少的纳米ZrO_2(Y_2O_3)粉体.与通常的共沉淀法相比。该方法制得的粉体因形成一种“包裹”结构,使得单斜相含量随煅烧温度的升高而减少,从而更有利于烧结.
In this study, we prepared a novel powder preparation method - alcohol - aqueous solution heating method to prepare nano-ZrO_2 (Y_2O_3) powder. The experimental results show that nano-ZrO_2 (Y_2O_3) powders with small particle size and less agglomeration can be obtained by selecting proper conditions. Compared with the common coprecipitation method. The powder obtained by the method forms a kind of “package” structure, so that the content of monoclinic phase decreases with the increase of the calcination temperature, thereby being more favorable for sintering.
