2223 phase growth in Pb-substituted Bi-Sr-Ca-Cu-O ceramic superconductors prepared via the combustion method
The combustion method is a simple and straightforward process ofceramic superconductors and is chosen as an alternative to the conventional solid state reaction. In the BSCCO system, the optimization of the growth of the 2223 phase has always been the goal of many researchers because of its high critical temperature (Tc). Previous studies have revealed that the 2223 phase growth is influenced by factors such as sintering time, temperature, presintering condition and stoichiometric composition. In this study, the ideal Bi:Pb ratio and the presintering parameters to maximize the 2223 phase were investigated.
