Phase-change substance, thermal control device and methods of use thereof
In an Mn-containing perovskite oxide which is a conventional phase-change substance (A1−xBx)MnO3, when the mixing amount x is increased, the transition temperature (Tc) is shifted to higher temperature side, but the slope of a change in the emittance become gentle and Δε (ε at higher temperature−ε at lower temperature) also become small. In the present invention, the compositional formula of the phase-change substance is the Mn-containing perovskite oxide represented by (A1−xBx)Mn1+yO3 with 0<y in which the Mn ratio is changed from stoichiometric composition, thereby shifting the transition temperature (Tc) to a higher temperature with the emittance characteristic thereof comparable to that of the phase-change substance having the composition which is not changed from stoichiometric composition.
