Description

X-ray diffraction data of Bi1.4Pb0.6Sr2Ca2Cu3.6O10+x samples show a sharp change near the annealing temperature of 845 degree C. Below this temperature a solid solution of (Ca0.867Sr0.133)2PbO4 is formed and prolonged annealing leads to transformation of the 2212 phase to the 2223 phase. Above this temperature, Ca2PbO4 is formed, and prolonged annealing leads to an irreversible transformation of both the 2212 phase and the 2223 phase to the 2201 phase
