Abstract

Abstract: Al₂O₃-Zro₂-SiC composites were prepared by RBAO technology and then fast-fired or conventionally-sintered. The materials obtained by both processes proved to have dense, fine-grained andhomogeneous microstructure, which gave rise to good mechanical properties. Fully dense and fiawfree materials were obtained after HIPing, therefore their properties were significantly improved.

Key words: alumina, composite, fast firing, mechanical properties
