<p>An aluminum nitride sintered product with a high thermal conductivity (at least 100 W/m.K) can be prepared at a sintering temperature of less than 1850 °C (often less than 1650 °C) using a sinterable combination of aluminum nitride powder with at least three sintering aids. The sintering aids include a source of a rare earth metal oxide, a source of an alkaline earth metal oxide, a boron source and, optionally, a source of aluminum oxide. The sinterable combinations may also be used to prepare cofired, multilayer substrates.</p> |
