Research Abstract
Dynamic control of the thermal conductivity in solids was studied to develop thermal switching materials. The thermal conductivity of Ti2O3 showing a metal-insulator (M-I) transition with sharp electrical conductivity changes was investigated with an aim to develop oxide materials capable of switching the thermal conductivity by the M-I transition. Buk ceramic samples of Ti2O3 were prepared by spark plasma sintering. A large thermal conductivity change of ca. 3 times from 400 °C to 800 °C was observed for Ti2O3 with its M-I transition.
