High-temperature oxidation kinetics of nanostructured thermoelectric skutterudite CoSb₃ under different environments.

ABSTRACT: Skutterudite CoSb₃ is an n-type thermoelectric material used in thermoelectric generators (TEGs) to recover and convert heat from various sources into electricity. For TEGs, such as CoSb₃, thermal stability is crucial, especially when exposed to high temperatures and varying environments. To synthesize high-purity nanostructured CoSb₃, an optimized solvothermal method was developed with detailed investigation of the influence of stoichiometry, solvent choice, and reaction duration on the formation mechanism, as revealed by Powder X-ray diffraction (PXRD). The thermal degradation behavior of the synthesized CoSb₃ was systematically analyzed in air and nitrogen atmosphere. The oxidation products were identified using PXRD, the microstructural chang
