Abstract: The effect of sintering on the structural and superconducting properties of the (Bi1.6Pb0.4)Sr2CaCu2O8 system has been investigated.The samples were prepared by solid-state reaction method with different sintering temperatures:820 °C, 825 o C, 830 o C, 835 o C, and 840 o C. The samples were characterized by X-ray diffraction (XRD), electrical resistance, and AC susceptibility measurement.XRD patterns showed that the Bi-2212 phase with orthorhombic unit cell was found in all samples.In general, no systematic changes in lattice parameters indicating increasing sintering temperature until 840 o C did not affect the lattice.The sample sintered at 840 °C showed the highest Tc-onset and Tc-zero, 84 K and 71 K, respectively.The sample with the sintering temperature of 840 °C also showed the highest AC susceptibility transition temperature, Tcχ′ (80 K).The peak temperature of the imaginary part of the susceptibility, Tp, for the sample sintered at 840 °C increased to 57 K.According to these study's findings, 840 °C is the most suitable temperature for sintering (Bi1.6Pb0.4)Sr2CaCu2O8 system.
