Provided is a method for producing ceramic for heat-radiating members, using as a raw material alumina powder containing at least 99.5mass% alumina (Al2O3) and having an average particle diameter of 0.2 to 1µm. The method comprises: a granularization step in which said powder is rendered into granul...
