Abstract
Prepare sintered aluminum nitride bodies having a thermal conductivity of at least 200 W/m-K 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. Sintered bodies having thermal conductivities in excess of 200, especially in excess of 270, W/m-K result from this process.
