Abstract

PURPOSE:To obtain the titled sintered body outstanding in thermal conductivity and high-temperature strength, by incorporating aluminum nitride powder with calcium sulfide as the sintering aid. CONSTITUTION:Aluminum nitride powder is incorporated with 0.1-10wt.% of calcium sulfide followed by mixing, forming and then sintering in a vacuum or under an inert atmosphere, thus obtaining the objective sintered body. The average particle size of the calcium sulfide is pref. <=5mum in terms of its dispersibility in the aluminum nitride powder. The sintering process may be carried out either in a pressurized state or under normal pressure.
