Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of producing aluminum nitride powder, in which the content of Fe is reduced in particular, on an industrial scale. SOLUTION: The method of producing aluminum nitride powder is characterised in that aluminum nitride powder is heat-treated at a temperature of 1,400 to 1,850°C under a reduced pressure of ≤10-2Torr.
