The high-Tc phase of Bi1.6Pb0.4Sr2Ca2Cu3Oy has been synthesized using an appropriate thermal procedure. D.c. electrical resistivity and X-ray diffraction studies have been done. The measurements show that a slow cooling process is necessary for a better control of the thermal process. The variation in Tc as a function of annealing time is also reported. Indexed X-ray diffraction patterns indicate the formation of high- as well as low-Tc phases.
