Synthesis and Characterization of Low Density Bi-2223 Superconductors via Co-Precipitation Method

Abstract:

High temperature Bi_1.6Pb_0.4Sr₂Ca₂Cu₃O_δ of low density has been synthesized via co-precipitation method and its electrical and structural properties have been studied. The optimum porosity of the samples was obtained using variety amount of sucrose C₁₂H₂₂O₁₁ which is used as supplementary filler. The electrical properties of superconductor such as critical temperature, T_c and critical current density, J_c were determined using the four-probe method. X-ray diffraction (XRD) was used to analyze the structural properties of the samples. The density of samples was measured using densitometer. The obtained results have revealed a significant influence of the pore presence in superconducting samples on the electrical properties. The T_c for low density Bi-2223 with 0.1g sugar sucrose is much higher compared to 0.05g, 0.15g and standard sample which is T_{c zero} is 98 K. The J_c for low density Bi-2223 with 0.1g sugar sucrose is 6 A/cm² at 60 K which is higher than high density samples. The crystallographic structure remains in the tetragonal form where a=b≠c for all samples.
