▎ 摘  要

NOVELTY - A graphene modified ceramic composite material is prepared by preparing (50-20 0):1 mass ratio of ceramic powder and graphene nanosheet dispersion, placing ceramic powder in the cavity of a pressure casting machine, placing graphene nanosheet dispersion in the cavity of a pressure casting machine, injecting graphene nanosheet dispersion under 20-50 MPa at injection speed of 0.5-5 meters/second for 10-180 seconds, mixing with ceramic powder, drying, and molding and sintering. USE - The method for preparing graphene modified ceramic composite material used for preparing article (claimed). ADVANTAGE - The method enables preparation of graphene-modified ceramic composite material having pressure injection pressure of 20-50 MPa, injection speed of 0.5-5 m/second and pressure maintaining time of 10-180 seconds.
