摘要：
Bi(1.6)Pb(0.4)Sb(0.0)6Sr(2)Ca(2)Cu(3)O(y) superconductors were processed by the solid-state reaction at 860 degrees C, varying the sintering time from 100 to 160 h. The structural characterization was carried out by X-ray diffraction and Raman spectroscopy, which showed that Bi(1.6)Pb(0.4)Sb(0.0)6Sr(2)Ca(2)Cu(3)O(y) samples have a mixture of interest B-2212 and Bi2223 phases. The sintering time strongly influences structural, morphological and electrical properties; the sample sintered by 130 h presents a volume fraction of 62% for the Bi-2223 phase, large grains (between 5 and 20 mu m) and a critical temperature of 107 K.
