| 英文摘要 | 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.
