Abstract

The effects of Ba-addition to the high-Tc phase in the Bi-Pb-Sr-Ca-Cu system have been studied for the samples with a starting composition of Bi:Pb:Sr:Ba:Ca:Cu=0.9:0.2:1.0:x: 1.0:1.6 heated at 850°C in air (x=0 to 0.10). Various amounts of BaCO₃ were added to the high-Tc phase with a composition of Bi:Pb:Sr:Ca:Cu=0.9:0.2:1.0:1.0:1.6. Ba-addition raises Tc; Tc(R~0)=122K and Tc(R=0)=120K for the sample with x=0.05 heated at 850°C for 60h. XRD and ICP analyses indicate that the high-Tc phase contains Ba of x≦0.05 as a solid solution.
