Influence of Reaction Temperature on the Densification Behavior of the SiC/B₄C Composites

Abstract:

In this investigation, the rare-earth oxide La₂O₃ combined with Al₂O₃ served as sintering additives and commercial α-SiC and B₄C powder were applied to fabricate SiC/B₄C composites by pressureless sintering. The results proved that combination of Al₂O₃ and La₂O₃ sinter additives were effective for densification of SiC/B₄C composites. The influence of sinter temperature on the phase constitution, micro-structure and densification behavior of SiC/B₄C composites was investigated.
