Abstract
The melting behavior of the 2212 phase in the Bi(Pb)SrCaCuO system has been investigated using DTA, XRD and EPMA. The effect of Pb and Ca on the melti ng of 2212 have also been discussed. The results indicate that the melting point of 2212 decreases monotonicaly with increasing Pb, however it reaches a peak value with the increase of Ca. 2212 melts incongruently into a liqu id and (Sr,Ca)CuO2, and the crystals formed when the liquid is quenched in air vary with the starting concentrations of Pb and Ca.
