Document Type and Number:
Japanese Patent JP5618734
Kind Code:
B2
Abstract:
To provide a method of producing a spherical aluminum nitride powder which has a large thermal conductivity and excellent filling property, and is useful as a filler for heat-radiating materials. [Means for Solution] The spherical aluminum nitride powder is produced by reductively nitriding a mixture of 100 parts by mass of an alumina or an alumina hydrate, 0.5 to 30 parts by mass of a rare earth metal compound and 38 to 46 parts by mass of a carbon powder at a temperature of 1620 to 1900°C for not less than 2 hours.
