Effect of Rare Earth Oxides on Densification and Mechanical Properties in β-SiAION Ceramics

Chen Hong

Abstract

The effects of mixed rare earth oxides on densification, microstructure and mechanical properties Dy-β-SiAlON ceramics were investigated. It was found that the densities and mechanical properties were improved while Dy'+ was half replaced by Sm3+, but there was no such effect found while replaced by Y3+. It was also observed that the growth of β-SiAlON grains was restrained while Sm2O3 was added.
