摘　　要：本实验用溶胶—凝胶法制备了平均颗粒尺寸30mm左右的Yb_2O3-ZrO_2超细粉,获得了粉体颗粒小、分布均匀,颗粒形貌较理想,无硬团聚的超细粉,并探讨了高分子表面活性剂对粉末性能的形响。In this experiment the Ytterbra stabilized Zirconia powder with a super - fine particle size (30 - 40nm) well, distribution and ideal particle shape and free agglom erate had been prepared by sol - gel. The effects of the polymer surfactant on the characteristics of powders were also discussed.
