Title:

METHOD OF PRODUCING ALUMINUM NITRIDE SINTER

Document Type and Number:

WIPO Patent Application WO/1990/012768

Kind Code:

A1

Abstract:

An aluminum nitride sinter can be produced at a relatively low heating temperature by mixing at least 20 % by weight of ultrafine aluminum powder having a mean particle diameter of 0.5 mum or less with other powdery raw materials, compression molding the resultant powdery mixture, heating the molded powder in a nitrogen atmosphere at 600 to 800°C to nitride the ultrafine aluminum powder, and sintering the molded powder thus treated by utilizing the heat of nitridation.
