Effect of prior heat treatment for commercial-grade aluminum nitride powder in gas atmospheres and activating additions on the structure and properties of hot-pressed ceramics based on it

Effects of reduction atmosphere and nano carbon powder addition on the deoxidization of injection molded aluminum nitride parts

“…It can be observed that, in addition to the carbothermal reduction effect of carbon, a slight incorporation of hydrogen in the atmosphere also had a minor effect on the loss of oxygen. The loss of oxygen with the addition of carbon in the green compact or introduction of a fraction of hydrogen in the nitrogen sintering atmosphere accounted for the improvement in the thermal conductivity of sintered AlN (Lai and Nagai, 1995;Koval'chenko et al, 2000;Watari, 2001).
