Abstract

Li addition was found to raise Tc up to 116K in the high-Tc phase in the Bi-Pb-Sr-CaCu-O system. But the role and behavior of Li has not yet been clarified. This study has been done for samples with starting compositions of Bi0.9Pb0.2Sr1.0Ca1.0Cu1.6LixOy with x=0.03 to 0.10 and heated at 825 to 840».C for 1 to 48h. ICP analysis showed that Li content decreased with increasing sintering time. The lattice constant a decreased at first and then gradually increased. On the other hand, the lattice constant c passed through a maximum around 4h.
