摘要：

Ceramic samples of nominal composition of BiSrCaCu2O5.5 were analyzed by an electron microscope equipped with an EDAX system. Compositions of phases C37, C30 and C24 (denoted according to the height of their elemental cells) were found to be Bi2.4Sr1.6Ca2Cu3Oy , Bi2.4Sr1.6CaCu2Oy and Bi2.4Sr1.6-kCakCuOy (k=0.4- 1.2) respectively. In most of analyzed volumes of the size of several cubic micrometers, mixtures of two or of all three phases have been found. A mechanism of formation of the C37 phase and of the phase mixtures is proposed. © 1990.
