Abstract: A method for preparing metal silicide-SiC composites is provided to produce nano-size metal silicide-SiC composites having excellent oxidation resistance and mechanical properties within a short time. A method for preparing metal silicide-SiC composites includes the steps of: pulverizing a mixture of a metal carbide and a silicon powder into nanopowder by a planetary ball milling method; applying pressure and heat to the nano-powdered mixture to synthesize a metal silicide-SiC composite, wherein the heat is generated by an induced current; removing the pressure and induced current from the synthesized metal silicide-SiC composite; and cooling the metal silicide-SiC composite.
