| Abstract: | In this paper, the preparation of the Bi system superconductor by the decomposing nitrates. solution method is described. The samples possessing superconducting transition with onset above 98 and the zeroresistance state at 78 K were successfully obtained. The resuits measured by SEM and X-ray diffraction show that the samples have various phases. |
