Description	Thermal and phase stability of selected doped multicomponent CoSb3 based skutterudites from macrocrystalline to nano-structured form have been studied using methods of thermal analysis (TA) and Knudsen effusion mass spectrometry (KEMS). The measurements have been performed on a Netzsch STA 409 CD/3/403/5/G apparatus, a specially-adapted type of the commercial STA 409 CD - QMS 403/5 Skimmer Coupling Instrument, described in [1], [2]. The results of TA and KEMS measurements, including data on phase transformations and evaporation characteristics of volatile elements, supported by measurements of diffusion profiles are summarized and discussed in view of a full understanding of the degradation processes.
