| Abstract: | A new technique named chemical coprecipitation- gel method of pnducing nano -sized ZrO2 based powders is intnduced in this Paper. By this method, high purity and ultra fine ZrO2 POwder or synthesised ZrO2 based powder with about 10nm equivalent diameter, lower than 0. 1wt% total content of impurities. Particles with high dispersity and very narrow size disribution can be produced using cheap materials and through convenient technological process. The characteristics of phase structure and sintering ability of the nano-sized ZrO2 powders are also investigated. |
