X-ray diffraction (XRD), EDAX, AC susceptibility and resistivity measurements has been used as characterization methods for the Bi-2223 monophase target with the starting stoichiometry Bi1.8Pb0.3Sr2Ca2Cu3.3Ox. Pressure parameter is playing an important role in obtaining good superconducting properties for this compound. Critical currents and activation energy has been calculated from susceptibility and magnetoresistivity curves, respectively. The results could be interpreted in terms of TAPS and TAFF models.
