Cu2Se looks like Black cubic crystals, with relative density 6.749 and melting point 1113°C. It is obtained by heating a stoichiometric mixture of copper and selenium in a vacuum quartz sealing tube, or by reduction of copper salts and ammonia solution of selenite with hydrazine hydrate. Used as semiconductor.
Copper selenide is a thermoelectric material that can be used for many industrial applications, including infrared detection and imaging.
Mainly used for preparing group compound semiconductors, copper selenide targets, and copper indium gallium selenium thin film solar cells.
