In this paper, the preparation of Bi 1.7-x Pb 0.3 Sb x Sr 2 Ca 2 Cu 2 O y (x = 0.05,0.1,0.15,0.2) superconductors was investigated. The effects of quenching and furnace cooling on Tc were studied. The highest Tc was 108.2K the result of. Differential thermal analysis, scanning electron microscopy and X-ray diffraction analysis were done, and the reasons for the formation of high T_c and low T_c phases were discussed and analyzed. In addition to adulteration
