AB - Mechanical alloying was carried out to produce CrSi2 thermoelectric compound using a mixture of elemental Cr33Si67 powders. An optimal milling and heat treatment conditions to obtain the single phase of CrSi2 compound with fine microstructure were investigated by X-ray diffraction and differential scanning calorimetry measurement. CrSi2 intermetallic compound with a grain size of 70 nm could be obtained by MA of Cr33Si67 powders for 70 hours and subsequently annealed at 650oC. Consolidation of the MA powders was performed in a spark plasma sintering (SPS) machine using graphite dies at 600~1000oC under 60 MPa. The shrinkage of MA samples during SPS consolidation process increased gradually with increasing temperature up to 1000oC and relatively significant at about 600oC. We tend to believe that these behaviors are deeply related to form a CrSi2 compound during heating process, as can be realized from the DSC measurement. Electrical conductivity and Seebeck coefficient of sintered bodies were measured up to 900oC. Seebeck coefficient and power factor of Cr33Si67 compact prepared by MA and SPS at 1000oC showed the maximum value of 125 μV/K at 400oC and 4.3 × 10−4 W/mK2 at 350oC, respectively.
