<p>A method for producing an aluminum nitride powder includes mixing an alumina powder having an average particle diameter of not more than 5μm; an eutectic melting agent; and a carbon powder are mixed to obtain a mixture thereof, and reductively nitriding the mixture by firing at a higher temperature than a melting point of the eutectic melting agent, while maintaining a nitrogen ratio within a range of 60 to 85 vol % in an atmosphere of mixed gases of nitrogen and carbon monoxide until a nitriding ratio of the alumina powder reaches at least 50%.</p> |
