摘要：

Ag2O doped and oxygen deficient YBa2Cu3O7-x (0<X<1) ceramics with various Ag2O concentrations up to 40wt.% were studied for the thermoelectric refrigeration use in the temperature range from 10K to 260K. The amount of the oxygen deficiency (X) was controlled by varying the thermal quenching temperature. The Seebeck coefficient S, the electrical resistivity rho and the thermal conductivity kappa were measured and the systematic dependence of these quantities and the figure of merit (Z) on Ag2O doping were observed.
