Abstract

Ti/Si/C powders were used to fabricate high purity Ti₃SiC₂ with the aids of Al by spark plasma sintering (SPS). The results showed that the dense Ti₃SiC₂ samples with <2 wt.% TiC could be rapidly synthesized from Ti/Si/C/Al mixtures at 1280 °C for 6-36 min. The sintering temperature and the sintering time was lower and shorter than that by hot isostatic pressing (HIP) or hot pressing (HP) from Ti/Si/C mixtures. The microstructures of Ti₃SiC₂ depend on the sintering temperature and holding times of SPS and can be controlled accordingly. The technological implication of this work is that, with the aids of Al, Ti/Si/C can be suggested to be the powder mixture to synthesize high purity Ti₃SiC₂ in addition to Ti/Si/TiC powder mixture.
