Abstract
The high T sub c of lead-doped Bi--Sr--Ca--Cu--O superconductor materials makes them very attractive for study. It has been found that most of the Pb escapes during sintering but it is still necessary to obtain the high T sub c . Tests were performed on Bi sub 0.96 Pb sub 0.24 SrCaCu sub 1.6 O sub 5+x to determine its structure and crystallization characteristics. The compound crystallizes at 685K in a highly distorted structure. After several crystal changes, it becomes the 2.4 nm bismuth-based superconductor at 825K. This phase decomposes at 1020K. Additionally, there is evidence of long range order in the liquid phase.
