Abstract: Al2O3-ZrO2(15vol%) nanometer composite powder was prepared by surface-induced precipitation under the condition of pH=5. Zeta potential and TEM were applied for characterizing the specimen. The results show that the structure of the composite powder calcined at 800℃ is tightness and uniform and the average size of ZrO2 particles combined on the surface of Al2O3 particle is about 30urn.

Key words: Al2O3-ZrO2, nanometer composite powder, surface-induced precipitation
