(Mo1-x-Crx)Si2 composite powders were successfully synthesized by ball milling of Mo, Cr and Si elemental powders. Effects of the Cr content, milling time and annealing temperature were investigated. X-ray diffraction (XRD) was used to characterize the milled and annealed powders. The morphological and microstructural evolutions were studied by scanning electron microscopy (SEM) and transmissio...

This review article gives an overview of the recent research directions in eco-friendly, non-toxic, and earth-abundant thermoelectric materials. It covers materials such as sulfides, tetrahedrites, oxides, silicides, copper iodine, Half-Heusler intermetallic compounds, nitrides, other environmentally friendly thermoelectrics. In all cases, their history, structure, general characteristics, prop...
