Reaction Routes

Lead-doped Bi-2223 superconductors were prepared by two main popular solid state reaction routes, viz. solid state diffusion reaction and the matrix method. Even though both routes produce single-phase materials superconducting at 110 K, the resistivity behaviors above Tc are found to be different. Aging/degradation behavior was studied in terms of Tc on both sets of samples stored in a desiccator for eight months. Our studies indicate that the synthesising routes play a major role in the preparation of high quality bulk Pb-doped Bi-2223 superconductors which are more resistant to degradation when exposed to humid conditions.
