摘要 Since the discovery of BiSrCaCuO superconductor, for stabilizing and promoting the formation of high Tc 2223 phase substituting a part of Bi with Pb is the most effective way. We have systematically studied the effect of the high valency cations V5+, Nb5+ and Ta5+ on the formation of high Tc 2223 phase and found that doping any of them can
