The effect of MgB 2 addition on the Eu 1 Ba 2 Cu 3 O 7 (EBCO) ceramics was systematically studied. Series of Eu 1 Ba 2 Cu 3 O 7 + x(MgB 2 ) samples (x = 0 wt.%, 0.05 wt.%, 0.1 wt.%, 1 wt.%, 3 wt.%) were prepared using traditional solid state method. X-ray powder diffraction measurements were used for phase identification. The lattice parameters and orthorombicity decreased with MgB 2 addition. A standard four point measurement method was used to determine transition temperatures T c of superconducting samples. T c values of the samples were decreasing with MgB 2 concentration. TGA results indicate thermal stability of doped samples.
