The relationship between thermal conductivity and intergranular oxide phase variation in AlN sintered by millimeter-wave heating was investigated. The thermal conductivity was increased with the decrease of a ratio of Al<SUB>2</SUB>O<SUB>3</SUB> to Yb<SUB>2</SUB>0<SUB>3</SUB>+Al<SUB>2</SUB>O<SUB>3</SUB> in the intergranular phase. When a high thermal conductivity of 210 W/(m⋅K) was obtained at 1973 K for 3 hrs under a mixed gas atmosphere of N<SUB>2</SUB> with 3 vol% H<SUB>2</SUB>, Yb<SUB>2</SUB>O<SUB>3</SUB> phase was observed as an intergranular phase, unlike conventional sintering.
