Lead telluride (Phoebe) is a compound of lead and tellurium (PbTe); it is a narrow gap semiconductor .
It occurs naturally as the mineral altaite .
It is often alloyed with tin to make lead tin telluride, which is used as an infrared detector material.
Lead telluride has good performance as a thermoelectric material, partly due to a low thermal conductivity and partly due to its electrical properties.
It has peak thermoelectric performance at high temperature and was used in spacecraft power applications.
