【Abstract】 In present paper the effect of doping some elements on the formation of the 2223 phase in Bi-system superconductors and their relationship to the superconductivity, were investigated. The experiment showed doping with those cation is benefit of 2223 phase formation of Bi - system high Tc superconductor, benefiting to enhance the superconductivity of 2223 phase.更多还原
