| Abstract: | AlN ceramics with high thermal conductivity is a very promising material for electronic substrates . Based on the mechanism of thermal conduction, the authors discussed the effect of several compound sintering aids on the densification and the thermal conductivity . It is shown by analysis that the removal of oxygen-related defects from AlN grains is significant to improve the thermal conductivity and to strengthen the densification. The oxidation reactions between AlN powder and oxide additives were described in this study. |
