NOVELTY - A graphene/metal/magnesium diboride composite with high intergranular connectivity, comprises 0.92-0.98 mol.% magnesium powder, 1.8-1.9 mol.% boron powder, 0.1-0.2 mol.% graphene powder and 0.02-0.08 mol.% metal powder. USE - Graphene/metal/magnesium diboride composite with high inter-granular connectivity (claimed). ADVANTAGE - The raw materials of the composite are readily available. The preparation method is simple and convenient, and effectively reduces magnesium diboride reaction temperature, and improves intergranular connectivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing graphene/metal/magnesium diboride composite with high inter-granular connectivity.
