Abstract:
    The invention discloses a method for making compact composite material of ceramics and metal with low specific density comprising the steps of, mixing homogeneously one or a plurality of powders capable of forming carbonization substance with one a a plurality of refractory carbide ceramic powders, and carbon or one or more substances containing carbon, moulding the mixture at atmospheric temperature, subjecting the enough amount of carbon dust to thermal treatment at high temperature, leaking the molten metal or alloys into ceramic frames by means of melting method, thus obtaining the compact composite materials.
