摘要：

Sintering characteristic and microstructure of Y2O3-DY2O3- doped anti-hydrolysis AlN powders synthesized by SHS method were studied. The results show that all kinds of secondary phases, such as Dy4Al2O9, Y4Al2O9, DyAlO3, Dy2O3 and DyN, will appear in the grain boundaries. The sintering temperature affects the microstructure and the kinds, amount and distribution of secondary phases; and therefore influences the thermal conductivity. AlN ceramic's thermal conductivity obtained at 1850 degrees C is 148W/m.K.
