Abstract

By using 24 GHz millimeter-wave irradiation, full densification of AlN added with Y₂O₃ was attained at 1700 °C, which is comparable to 28GHz-wave irradiation. Thermal conductivity of a resultant sample exceeded 200 W/mK, which is the highest value in AlN fabricated in non-reducing atmosphere.
