The field of renewable energy technology has been attracted a lot of interest due to depletion of fossil fuels, energy crisis and global warming. Thermoelectric technology is one of the best renewable energy technologies, which can convert waste heat to electrical energy or electrical to heat in eco-friendly manner. Thermoelectric material (TE) properties are directly influenced by preparation techniques. However, the complexity and cost for fabrication of TE materials have considerable high with conventional methods. Hence, we are focused on fabrication of BiSbTe materials by using water atomization which is simple and easy process control. Subsequently, as-prepared powders was consolidated at different temperatures (300, 350, 400 and 450 oC) by well known advanced technique such as spark plasma sintering (SPS). The crystal structure and cross-sectional microstructures were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and EBSD techniques. Thermoelectric and mechanical properties of sintered bulk samples were investigated systematically.
