Title:
PROCESS FOR PRODUCING OF MASSIVE MIXTURE OF ALUMINUM NITRIDE AND ALUMINUM
Document Type and Number:
Japanese Patent JP2009235498
Kind Code:
A
Abstract:

To provide a process for producing a mixture of aluminum nitride and aluminum at low production cost.

The process for producing the mixture of aluminum nitride and aluminum involves a first heat-treating step of heating an aluminum powder 21 and an aluminum piece 20 which have been charged in a vessel 13 to a temperature equal to or higher than the melting point of aluminum in a nitrogen atmosphere to thereby produce a massive mixture of aluminum nitride and aluminum. The aluminum powder 21 has an oxide film formed on the surface thereof. The oxide film may be a natural oxide film. The ratio of the amount of the aluminum powder 21 to the amount of the aluminum piece 20 may be, for example, 0.1 or less by weight.
