Abstract: A method of manufacturing a metal hybrid, heat-dissipating material includes the steps of (a) preparing a spherical metal powder and a flake graphite powder having an aspect ratio greater than 1, respectively; (b) preparing a powder mixture by inserting only the spherical metal powder and the flake graphite powder into a container, followed by dry mixing the powder mixture using a multi-axial mixing method for rotating or vibrating the container about two or more different rotation axes without any liquid input and without any mixing aids; (c) manufacturing a green compact by pressing the powder mixture; and (d) sintering the green compact to provide the metal hybrid, heat-dissipating material.
