摘要	Al2O3-ZrO2 (Y2O3) AZY nano-composite powder with a microstructure of zirconia grains buried in amorphous alumina was prepared by a novel co-precipitation method. Hard agglomerates in the powder can be easily broken down as a result of the amorphous alumina on the surface of primary particles, which is soluble in NaOH solution. 98.9% relative density was reached at 1300 degrees C, and grain abnormal growth emerged accompany with density decrease at 1550 degrees C for the de-agglomerated AZY composite powder. A small amount of sodium impurity residual in NaOH solution treated powder developed a dense microstructure with alumina grain in platelet shape at 1300 degrees C. The morphology and size of alumina platelet did not change much with the sintering temperature increasing. (C) 2015 Elsevier B.V. All rights reserved.
