The effect of grain boundary segregation and second phase distribution on the thermal conductivity are discussed. The Er2O3-CaO- and the Yb2O3-CaO- AIN ceramics have a higher thermal conductivity than the CaO- and the Y2O3-CaO- AIN ceramics. This is explained on the basis of the free energy of formation (Delta G degrees), the vaporization of the sintering additives and the microstructural development. Oxidation of freshly cleaned surfaces of those AIN ceramics was studied.
