Description

An AlN ceramic was sintered with a dopant of Y2O3 under a reducing nitrogen atmosphere with carbon. The ceramic exhibited a high thermal conductivity, 272 W/mK. The value was equivalent to the experimental value of its single crystal (285 W/mK). The oxygen content of the sample was very low, 0.05 mass%. The microstructure was characterized by a high-resolution transmission electron microscope (HR-TEM).
