HIGH-HEAT-CONDUCTION COMPOSITE WITH GRAPHITE GRAIN DISPERSED AND PROCESS FOR PRODUCING THE SAME

摘要

A composite with graphite grains dispersed therein produced by solidifying of graphite grains coated with a metal of high heat conduction coefficient, such as silver, copper or aluminum, wherein the graphite grains have an average grain diameter of 20 to 500 µm, and wherein the graphite grains and the metal are used in a volume ratio of 60/40 to 95/5, and which composite has a heat conduction coefficient of = 150 W/mK in at least one direction thereof.
