Determination of the optimum sintering temperature for the Pb-doped Bi 2223 phase superconductors prepared by the combustion method
Abstract
The combustion method promises to be a competing technique in thepreparation of bulk high Tc superconductors. Like the solid state method it requires only simple instrumentation but has an advantage over other methods in that the technique is less tedious and shorter time is required to prepare the samples. The chemical set-up also ensures the homogeneity of the samples on the atomic scale. The optimum starting stoichiometry and combustion and dehydration temperature has already been found. Here we report on the determination of the optimum sintering temperature for the production of Pb-doped Bi 2223 superconductors by combustion method.
