In this study, the effects of Nb substitution on the Bi-based superconducting materials has been investigated.
The X-ray diffraction measurement indicated coexistence of Bi-2212, Bi-2223 phases and some impurity
phases of CuO, CuNb2O6, CaNb2O6, CaCuO2 and Sr5Nb5O16. With increasing Nb content, impurity phases
consistent with the Nb element appeared in the samples. Also with increasing Nb content the Bi-2223 phase of
samples gradually was decreased and in contrast, the Bi-2212 phase was increased. From the SEM results we
saw that with increasing of Nb contents, the crystal structure of the samples slightly was changed because of
the disrupted grain growth.
