COMPOSITE AND COOLING DEVICE

摘要

The present invention provides a composite of a mixture containing: a ceramic material having vanadium dioxide and/or vanadium dioxide doped with another element as the principal component thereof; and vanadium pentoxide and/or a glass material containing vanadium having a valence of five. It is possible to use this composite in a cooling device which is usable without a power supply, exhibits excellent cooling efficiency, and has high heat-cycle resistance.
