Graphene ceramic composite material prepared based on 3D printing and preparation method thereof
The invention provides a graphene ceramic composite material prepared based on 3D printing and a preparation method thereof, and belongs to the field of preparation of ceramic composite materials. Thegraphene ceramic composite material is prepared from three raw materials, namely Al2O3, SiC particles and graphene. The preparation process mainly comprises the steps of ball-milling mixing, slurry preparation, 3D printing, drying and microwave sintering. The preparation method has the main advantages that a method combining a 3D printing technology and microwave pressure sintering is adopted, after sintering, aluminum oxide and silicon carbide form a nano ceramic composite material, graphene modifies silicon carbide aluminum oxide ceramic, and the prepared composite material has good fracture toughness, electrical conductivity, thermal conductivity and the like. The ceramic composite material prepared by the method is simple in process and high in universality, the mold-free additive manufacturing of the ceramic composite material is realized, the production cost is greatly reduced, and the economic benefit is good.
