Poster: Bi-based superconductors with nanosize dopants
Original language description
It has been widely accepted that Ag-additives reduce the partial melting temperature and thereby accelerate the formation rate of Bi-2223 phase, reduce porosity, improve the mechanical properties and the weak links connecting superconducting grains. Nano-metric size particles have diameters in some range as magnetic pinning centers in the HTS. The influence of the nanometer Ag particles on Bi-2223 phase formation, microstructure and transport properties of samples have been studied. Samples with nominalcomposition Bi3.2Pb0.8Sr4Ca5Cu7Ox were prepared by solid state synthesis. Ag was used in three different weight percentage 5, 10 and 15. Ag powder was added to the initial mixture or after second calcination.
