The characterization of the ceramics prepared by the conventional solid-state reaction method were done by resistance-temperature measurements, XRD, SEM and density analysis. Low levels of Zn substitution of Ca caused significant changes in the properties of the ceramics. The low-T-c superconducting properties were enhanced and the fraction of the low-T-c (2212) phase were found to increase at x = 0.15 level of Zn substitution at 830 degrees C sintering temperature. Zero resistance was observed only in sample D with x = 0.15 and the T-c was determined as 92 K. The SEM micrographs and the density analysis have shown that this was the densest packed ceramic.eninfo:eu-repo/semantics/closedAccessBi-based SuperconductorsZn SubstitutionScanning Electronic MicroscopyX-ray DiffractionArticle10.1007/s10948-009-0491-82287497542-s2.0-72449148756Q3WOS:000271201900007Q3
