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