Abstract

High-temperature X-ray measurements were carried out on Bi-Sr-Ca-Cu-O. It was found that the 30 Angstrom phase showed incongruent melting forming new crystalline phases which differed depending on the compositions. Crystallization from the melt by cooling first produced the 30 Angstrom phase on solidification and then the 24 Angstrom phase crystallized around 730°C. Crystallization from the glassy phase by heating started at 430°C and led to the 24 Angstrom phase, which changed to the 30 Angstrom phase above 800°C. As a rule, low-temperature crystallization from the amorphous phase takes place below 730°C to form the 24 Angstrom phase in Bi-Sr-Ca-Cu-O.
