The present study was focused on the analysis of the electric and thermal properties of spark plasma sintered thermoelectric material. The crystal structure, microstructure, electric and thermal properties of the sintered body were evaluated by measuring XRD, SEM, electric resistivity, Hall effect and thermal conductivity. The sintered body showed anisotropic crystal structure. The c-axis of the crystal aligned in a parallel direction with applied pressure during spark plasma sintering. The degree of the crystal alignment increased with increasing sintering temperature and sintering time. The electric resistivity and thermal conductivity of the sintered body showed anisotropic characteristics result from crystal alignment.
