纳米Z_rO_2超细粉的制备及表面改性

PREPARAION AND SURFACE MODIFICATION OF Z rO 2 NANOMETER-SIZED POWDER

通过加入适宜的分散剂，采用共沉淀法制备了纳米级ＺｒＯ２超细粉，其粒度分布均匀，且分散性好，所得粉体进行了表面改性，使粉体表面由极性转变为非极性。

Z rO 2 nanometer-sized powder was prepared by chemical coprecipitation method using dispersant. It is shown that nanometer-sixed powder is homogeneous partical size distribution and easy dispersity. The surface of Z rO 2 the nanometer sized powder was modificated with stearic acid. The polarity of Z rO 2 nonometer-sized powder was changed.
