Abstract

The formation of the 37 angstrom (high-Tc) phase has been studied for Bi:Pb:Sr:Ca:Cu=0.9:0.2:1:1:1.6. The authors obtained the high-Tc phase crystallizing homogeneously in the Pb-induced modulation mode as reported previously. The solid phases formed after each firing treatment at above 795°C were identified, and the melting points of various combinations of these were measured. As a result, the lowest liquid formation temperature was 825°C for a combination of the 24 angstrom phase and Ca2PbO4. The liquid formation and formation of the Pb-substituted 30 angstrom phase seems to be the initial step in formation of the 37 angstrom phase.
