Abstract

The melt quenched method was applied in the fabrication of Bi_1.6Pb_0.4Sr₂Ca_n−1Cu_nO_y superconducting ceramics with n = 2.0, 2.5, 3.0 and 3.5. The samples were prepared as determined by its stoichiometric composition by melting it at 1080⁰C. The melts were poured immediately onto a stainless steel plate and quenched to room temperature. The samples were ground, pelletized and annealed at a constant temperature of 840⁰C for 24 hours. Tc SEM and XRD measurements were made. XRD results showed the coexistence of the low Tc, high Tc and several non superconducting phases. An increase in Ca and Cu facilitate the growth of the high Tc phase.
