Abstract:
A process for producing aluminum nitride comprising forming a mixed powder comprising, when the whole weight thereof is set to be 100% by weight, 50 to 97% by weight of a bulky aluminum powder composed of aluminum or an aluminum alloy powder whose sieve opening of JIS is not less than 210 .mu.m (70 mesh) and a balance of 3 to 50% by weight of a nitriding accelerator powder composed of at least one kind of an aluminum alloy powder including magnesium in an amount of not less than 0.5% by weight whose sieve opening of JIS is less than 210 .mu.m (70 mesh), and then nitriding directly the mixed powder under a nitrogen gas atmosphere at a temperature ranging from 500 to 1,000.degree.
