PRODUCTION OF METAL NITRIDE SINTERED COMPACT

摘要

PURPOSE:To obtain phenomena of gradual thinning of thickness of lining in a furnace with repetition of burning in the case of burning a mixture of a metal nitride powder and a metal oxide as a sintering auxiliary in a furnace having an inner lining consisting of a carbonaceous member. CONSTITUTION:A mixture of a metal nitride powder such as aluminum nitride or silicon nitride and a sintering auxiliary such as calcium oxide or barium oxide is burnt in a furnace having an inner lining consisting of a carbonaceous member in a nitrogen-containing gas atmosphere having 5-70mol% CO.
