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.
