β¦ Synopsis
SiCβbased electroconductive composites containing 10 and 30 vol% MoSi~2~ particles were hot pressed at 1900Β°C. The MoSi~2~ particles, besides increasing the electrical conductivity of the silicon carbide matrix, acted as reinforcement for the material. For the composition containing 30 vol% of MoSi~2~ (see figure), the roomβtemperature strength was 825 MPa, the fracture toughness 4.8 MPaΒ·m^0.5^ and the electrical resistivity 1.3Β·10^β3^ OhmΒ·cm.
