The addition effects of Pb, Ba and Li to the 2223 phase in the Bi-Sr-Ca-Cu-O system on the properties and the formation process have been reviewed.The incorporation of Pb and Ba into the 2223 phase and the increase in Tc has been experimentally discussed.The substitution sites of the elements have been interpreted on the basis of the results of the equilibrium phase diagrams for the 2201 phase reported so far.The formation process of the Pb and Pb+Ba doped 2223 phase has also been discussed with particular attention to liquid formation and wettability.
