Abstract
We report the enhancement of thermoelectric power factor in composite of SiGe-CrSi2. P-type SiGe- CrSi2 was synthesized by mechanical alloying and sintering method. In order to achieve nanocrystalline structure composite powder was prepared by high energy ball milling. Prepared powders were sintered at different press conditions to optimize for maximum power factor. The crystal structure and phase formation of SiGe and CrSi2 alloys in the composite were investigated using x- ray diffraction analysis. The electrical conductivity, Seebeck coefficient and thermal conductivity of sintered samples were measured from room temperature to 850 C. The result shows about 50% improvement in thermoelectric power factor of SiGe-CrSi2 compared to SiGe alloy.
