The study aims to explore a new synthesis method for silver chalcogenide compounds and assess their thermoelectric properties.
Synthesis of Ag2S0.4Te0.6 compounds through powder-metallurgical techniques, including mechanical alloying and spark plasma sintering.
Investigation of the effects of different sintering temperatures on the materials' microstructures and properties.
Characterization of thermoelectric performance, specifically power factor and zT values, at various temperatures.
The sample sintered at 600 °C achieved the highest power factor due to optimized electrical transport, with zT values of approximately 0.32 at room temperature and 0.50 at 473 K.
The study demonstrates that powder-metallurgical processing enhances the thermoelectric performance of silver chalcogenides significantly.
