Document Type and Number:
Japanese Patent JP2006131492
Kind Code:
A
Abstract:

To efficiently produce an AlN powder having a small average particle size, a small specific surface area and a low oxygen content.

In a production method of the aluminum nitride powder, a mixed powder containing 100 pts.wt. aluminum nitride raw material powder and 0.01-15 pts.wt. carbonaceous substance is subjected to a first heat-treatment at 1,400-1,600°C in a non-oxidative atmosphere with a carbon dioxide gas concentration of 0-10 vol.% and subsequently to a second heat-treatment at 500-800°C in an oxidative atmosphere.
