Crystalline Phases During the Melting of Bi2Sr2CaCu2OX
Keyword(s):
ABSTRACTThe melting of Bi2Sr2CaCu2Ox material has been studied by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) in order to study the phases that formed in the high temperature regions. Two distinct phases of (Sr1-xCax)CuO2 and (Sr1-xCax)2CuO3 have been observed in the Bi-rich matrix depending upon quenching temperatures. Crystallization from the melt by fast cooling usually produce the co-existence of Bi (2201) and these Sr-Ca-Cu-O phases.
