摘要：

MgO-ZrO2 nano-sized powders have been synthesized via the co-precipitation route using ammonia, ammonium carbonate and ammonium hydrogen carbonate as precipitant, respectively. The three different powders were characterized by TG-DSC, XRD and SEM. And the sinterability behavior of each powder also has been investigated. The results indicated that uniformly dispersed and much looser MgO-ZrO2 nano-sized powders could be obtained when the ammonium carbonate, especially the ammonium hydrogen carbonate were used. When ammonia was used, some agglomeration could be observed. The crystalline grain size of the three powders is closed to each other. Due to the existing of agglomeration, the sintered samples prepared by using ammonia as precipitant exhibited poorer sinterability than that of using carbonates as precipitant.
