  • Abstract
    The effect of excess of Ca and Cu on superconducting and electrophysical properties of Bi-2223 ceramics was investigated. It was found that a certain excess of Ca and Cu in the nominal composition with relation to the stoichiometric one improves the superconductive properties of the ceramics which results from the developing of dense net of intergranular contacts during formation of ceramics microstructure
