内容記述 | This paper describes the microstructures and thermoelectric properties of Co_<0.97> Cr_<0.03> Sb_3 ribbons. The ribbons were fabricated by casting on a rotating copper roll at the various surface velocities from 3 to 50m/s, and then annealed at 873K for 10.8ks. X-ray diffraction measurements, scanning electron microscopic and transmission electron microscopic observations revealed that the microstructures of ribbons depend on the surface velocity. Small amounts of the CoSb_2 type structure appear together with the large amounts of the CoSb 3 type structure in the case of the surface velocity below 1Om/s, whereas the CoSb_3 type structure alone appears above 20m/s. The crystal grain size becomes small with increasing in the surface velocity. The thermoelectromotive force and electrical conductivity, which were measured under a vacuum, were the largest for 1Om/s among the various surface velocities, and thus the power factor was also the largest for 1Om/s. | |||||
