Abstract

The effect of Li-addition to the low-Tc phase in Bi-Sr-Ca-Cu-O system have been studied for the samples with nominal compositions of Bi:Sr:Ca:Cu:Li=2:1.5:1.5:2-x:x heated at 720 to 845»C for 12 to 24h in air (x=0 to 0.8). The Li-addition promotes the formation of the low-Tc phase. Single phase of the low-Tc phase was obtained for the sample with x=0.2 to 0.4more easily than the sample with x=0. The lattice constant c of the low-Tc phase increases as the Li content increases. As the heating period becomes longer, the amount of Li content in the low-Tc phase decreases.
