PRODUCTION OF ALUMINUM NITRIDE POWDER

PURPOSE:To obtain low-oxygen low-carbon AlN powder and to facilitate the production of a sintered compact by specifying the viscosity of a powdery mixture of alumina with carbon, etc., and caked bodies of the mixture when the caked bodies are heated in an N2-contg. atmosphere to produce AlN.
