ALKALINE EARTH FILLED NICKEL SKUTTERUDITE ANTIMONIDE THERMOELECTRICS

摘要

A thermoelectric material including a body centered cubic filled skutterudite having the formula A_xFe_yNi_zSb₁₂, where A is an alkaline earth element, x is no more than approximately 1.0, and the sum of y and z is approximately equal to 4.0. The alkaline earth element includes guest atoms selected from the group consisting of Be, Mb, Ca, Sr, Ba, Ra and combinations thereof. The filled skutterudite is shown to have properties suitable for a wide variety of thermoelectric applications.
