PROCESS FOR SINTERING ALUMINUM NITRIDE TO A HIGH THERMAL CONDUCTIVITY AND RESULTANT SINTERED BODIES

摘要

Sintered aluminium nitride bodies having a TC of at least 200 W/m.K are prepared by sintering under non-reducing conditions and controlling interrelated parameters such as binder burnout atmosphere, heating rate, sintering temperature, time at sintering temperature, cooling rate and cooling temperature. The sintered bodies may also have a TC in excess of 270 W/m.K.
