Abstract: The thermoelectric phenomenon in the reference (pristine) and BN-added EuBa2Cu3Oy high- temperature superconductors have been studied. A series of 4 compounds was prepared by the solid-phase synthesis method. The phase evolution of the prepared materials was analyzed by XRD, and the SEM/EDX technique was employed to investigate the microstructure and elemental composition of the specimens. The temperature dependence of resistivity (p) and Seebeck coefficient (S) was measured in the range of300-1000 K. Power factor (PF) values were calculated for this temperature area. BN addition led to an enhancement of the PF at 973 K from 0.053 mW/m-K2 for the reference sample to 0.075 mW/m-K2 for the 0.15 wt.% BN- added EuBa2Cu3Oy.
