| Description | CoSb3 based skutterudites containing doping elements are promising candidates for thermoelectric aplications.The presence of Nd and Pr (their mixture known as didymium (DD)) or other elements like Sr, Ba, Yb as dopants in skutterudites leads to high efficient thermoelectric materials but the volatile elements (Sb, Sr, Yb, etc.) can evaporate at operation conditions, leading to structure changes, negatively influencing the thermoelectric properties. To gain information on the thermal and phase stability of DD and Fe containing CoSb3 based skutterudites, measurements by means of thermal analysis and Knudsen effusion mass spectrometry were performed. |
