Abstract
The growth process of the (2223) phase in Bi-Sr-Ca-Cu-O has been studied for oxides with nominal composition Bi2Pb0.6Sr2Ca2Cu3O x prepared by sintering at 835∼855°C for 5∼160 h in air. The partial melting which starts to occur at T pm≃842°C enhances the growth rate of the (2223) phase and produces a nearly single phase within 40 h. However, it causes a disturbance in current paths and suppresses the value of T c(ρ=0) below 100 K. The sample which has the highest T c(ρ=0) and the nearly single (2223) phase is obtained by sintering at a temperature just below T pm for a long period of time.
