Effect of B₄C Content on Densification Behavior of SiC-B₄C Ceramics

Abstract:

The SiC-B₄C multi-phase ceramics was fabricated by gas-pressure sintering technology. The rare-earth oxide Al₂O₃ combined with Er₂O₃/SiO₂ was served as sintering aids. The results were shown that the combination of Al₂O₃/Er₂O₃/SiO₂ sintering additives were effective for densification of SiC-B₄C multi-phase ceramics. The influence of B₄C content on the phase constitution, microstructure and densification behavior of the SiC-B₄C multi-phase ceramics were detailed. The lose weight and volume shrinkage rate of SiC-B₄C multi-phase ceramics had similar evolvement trend when B₄C content increased. Keywords: Gas-Pressure Sintering, SiC-B₄C multi-phase ceramics, densification behavior.
