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 own good electrical conductivity, however thermal conductivity is bad, which is perfect thermoelectric materials.  Usual production methods are hot-press, zone-melting, HPVB, Czochralski.
