NOVELTY - Preparation of a graphene-ceramic composite material involves uniformly mixing magnesium powder and ceramic powder in the mass ratio of 1:3-9, carrying out combustion reaction of the obtained mixture in carbon dioxide gas with pressure of 0.5-5 MPa, and sintering the obtained powder. USE - Preparation of graphene-ceramic composite material. ADVANTAGE - The method is simple, short, economical and produces graphene-ceramic composite material having uniform component structure and excellent performance. The process uses in-situ deposition composite magnesium and carbon dioxide gas-solid reaction characteristics, which enables uniform mixing of the graphene and ceramic powder.
