Studies on sintering effect on the structural and transport properties of (2223) phase
چکیده انگلیسی

(2223) phase is synthesized by solid state method. The X-ray diffraction technique, scanning electron microscope, electrical and thermoelectric power measurements were used to characterize the prepared samples. The samples are sintered from 1123 K to 1143 K and the effect of sintering on the structural and transport properties was investigated. All the above measurements showed that in the samples, there is nearly single (2223) phase. The Seebeck coefficient measurements shows that all the samples under investigation are p-type materials with hole carriers predomination over the measured temperature range. Using the electrical resistivity and TEP data, the power factor S2/ρ was calculated and exhibits good indication to wide application of the investigated compositions as thermoelectric materials.
