N2 - Promising materials for thermoelectric (TE) applications include skutterudites. The TE efficiency characterized by the ZT factor is only a partial route to the development of TE devices. The other part involves the thermal stability because the materials contain volatile elements such as Sb, Yb, etc. which can evaporate at operation conditions and negatively influence the TE properties. A serious attention is focused on study of doped bulk and nanostructured CoSb3 based skutterudites, especially those containing didymium. Coupling of thermal analysis and Knudsen effusion mass spectrometry is an effective tool for investigation of phase transformations and vaporization characteristics of the volatile components. This, supported by microstructure measurements as well as by investigation of master CoSb3 alloy, leads to evaluation of long term operation stability of the TE materials.
