In the present study, the powder metallurgical fabrication of thermoelectric materials has been studied with specific interest to control the microstructure by the mechanical grinding process. The thermoelectric powders with a various particle size distribution were prepared by the combination of the mechanical milling and blending processes. The specific electric resistivity of the sintered bodies mainly depended on the orientation of the crystal structure rather than the particle size of the raw powders.
