Abstract

The compaction and sintering behaviour of nanosized and well-dispersed Y-TZP/Al₂O₃ composite powders have been investigated. It has been found that the composite powders contained no hard agglomerates, and after compaction, all soft agglomerates are fragmented. The green density of the compact was found to decrease with the increase of alumina content. The composite powder compacts containing less than 20 mol% alumina can be sintered at not higher than 1350 °C to 99% of their theoretical densities. The densification behaviour of the composite powders show duplex shrinkage peak characteristics for the composites containing not less than 15 mol% alumina.
