NOVELTY - Preparing a superconductive plate involves modifying a graphene powder by an aerosol thermal decomposition method for an aeronautic aluminum alloy powder, and coating the aviation aluminum alloy powder uniformly and densely on the surface of graphene. The mixed powder is sintered by spark plasma sintering, and made into sheet by mechanical plastic deformation rolling method. The superalloy is finally prepared by coating upper and lower surfaces of the superconducting plate with an antibacterial layer. USE - Method for preparing a superconductive plate for refrigerator (claimed). ADVANTAGE - The method enables to prepare a superconductive plate for refrigerator, which has high thermal conductivity, accelerates freezing of foods in the refrigerator freezer, and is convenient for energy saving and environmental protection.
