· Cu2Sb

Cu2Sb is an intermetallic compound combining copper and antimony, belonging to the family of binary metal compounds studied for their potential in thermoelectric and electronic applications. This material is primarily investigated in research contexts for thermoelectric energy conversion, where it may serve as a component in cascaded thermoelectric systems or intermediate-temperature power generation devices. Cu2Sb and related copper-antimony phases are of interest to materials scientists exploring alternatives to traditional thermoelectric materials, though widespread industrial adoption remains limited compared to established bismuth telluride or skutterudite systems.
