Fabrication of MoSi₂-SiC Composites by a Spark Plasma Sintering Method

Fully dense MoSi₂-SiC composites were fabricated from the mixed powder of the elemental constituents by a spark plasma sintering method. The sintering and densification of the Mo-Si-C mixed powder are accomplished through three processes. In particular, it proceeds rapidly by the formation of MoSi₂. The most suitable temperature for the fabrication of MoSi₂-SiC composites depends on the content of SiC and increases with the content of SiC increasing. As a result, fully dense MoSi₂-SiC composites can be prepared without difficulty by a spark plasma sintering method.
