摘要: In the present work, nano-ZrO2∕CoSb3 composites were fabricated by milling ZrO2 and CoSb3 powders hot pressing at different sintering temperatures. For prepared compacts, phase purity, microstructure, temperature-dependent thermoelectric properties characterized. The effect of nano-ZrO2 dispersion on composite electrical conductivity thermal is strictly clarified comparing transport nondispersed dispersed identical porosity, so that porosity parameters could be eliminated. insulating inclusion itself also considered eliminated using effective media theories. It clearly verified charge carrier scattering phonon occur simultaneously to lower due introduction inclusions. investigated show higher existe...
