Abstract

In this paper, the rare-earth oxide Al₂O₃ combined with La₂O₃ served as sintering additives and commercial α-SiC powder were applied to fabricate SiC ceramics by pressure-less sintering technology. The results proved that combination of Al₂O₃ and La₂O₃ sintering additives was effective for densification of SiC ceramics. The influence of sintered additives content on the phase constitution, microstructure and sintering behavior of the SiC ceramics was detailed. The relative density, lose weight and volume shrinkage rate of SiC ceramics had similar evolvement trend with the increase of sintered aids content.
