在化学共沉淀法制备细晶PSZ陶瓷的基础上，用工业ZrO2作原料，以MgO、Y2O3、CeO2及α-Al2O3作为复合稳定剂及添加剂，采用机械球磨混合法，并在制备过程中部分用去离子水代替乙醇作为球磨介质，探讨了水磨混合法制备粉料的可行性．实验结果表明：在较低的固溶烧结温度（1550℃）下，经1100℃适当时间热处理，亦可制备出具有较好力学性能的细晶PSZ陶瓷材料，其室温强度约700MPa，断裂韧性在15MPa·m1／2左右；在（180℃，1MPa）水热条件下，采用CeO2作复合稳定剂的PSZ陶瓷材料要比Y2O3复合稳定的PSZ材料更具良好的抗水化性．
Compared to fine-grained PSZ ceramics prepared by coprecipitation, the costabilized (Y, Mg)-PSZ and (Ce, Mg)-PSZ wigh MgAl2O4 spinel additions were developed, in
which industrial zirconia was used as the main starting material. Powders were prepared by mechanical milling-mixing process. During mixing process, distilled water was partially used as
ball-milling medium instead of ethanol. Feasibility for milling-mixing in distilled water was studied. The experimental results showed that fine-grained PSZ ceramics sintered at low solid
solution temperature (≤1550℃) could be achieved by mechanical mixing process, as well as coprecipitation. These materials had good mechanical properties: the flexural strength and
fracture toughness at room temperature were about 700MPa and 15MPa·m1/2, respectively. After hydrothermal treatment (180℃, 1MPa, in distilled water) up to 20h, (Ce, Mg)-PSZ materials
exhibited much better thermal stability than (Y, Mg)-PSZ ceramics.
