Abstract
In this study, a core-shell composite powder with Mo as the shell material and beta-SiC as the core material was produced via chemical vapour transport caused by the hydrogen reduction of Mo oxide. Using this core-shell composite powder, a Mo silicide composite with uniformly dispersed beta-SiC was fabricated by pressureless sintering at 1400 degrees C. The relative density of specimens sintered for 10 hours was 96.1% and the electrical resistivity was 4.68 x 10(-5) Omega m. It was concluded that a beta-SiC dispersed molybdenum silicide composite with enhanced electrical resistivity was successfully fabricated at a relatively low sintering temperature using the core-shell composite powder.
