Abstract
The effect of Ag substitution on the properties of high-temperature superconductor Bi1.7Pb0.3Sr2Ca2−x Ag x Cu3O y system have been investigated. The electrical and structural properties of the samples, prepared by the conventional solid-state reaction method, have been characterized by X-ray diffraction (XRD), electrical resistance and scanning electron microscopy (SEM) studies. XRD analysis reveals a multiphase structure of the samples, whereas SEM micrographs indicate some morphological changes induced by silver addition. It was found that an increase of the amount of Ag2O addition leads to an enhancement of the critical temperature and the percentage of Bi-2223 phase in the phase mixture.
