| ABSTRACT |
|
The properties and sinterabilities of the ZrO2-3m/oY2O3 powders prepared by coprecipitation were investigated. The specific surface area and the total proe volume were decreased with the increasing pH of the sediments. The partially stabilized zirconia powders were fine powders with high specific surface area. The powders prepared by freeze drying method showed low tendency for agglomeration, and the powders obtained from spray drying method showed fine powders and narrow pore size distribution. At 140$0^{circ}C$, their relative densities were up to 96%. |
