Bismuth Telluride

Bismuth telluride can be black powder or gray rod, which is a kind of semiconductor material. The another name is bismuth(III) telluride. It owns good electrical conductivity, however thermal conductivity is bad, which is perfect thermoelectric materials. Thermoelectric material is function material that realize direct interconversion between thermal energy and electric energy. Usual production methods are hot-press, zone-melting, HPVB and Czochralski. It can process into films too.
