Abstract
The sintering time effects on the structure properties of two distinct phases of Bi2Sr2Can–1CunOx, namely, Bi-2223 and Bi-2212 phases prepared by the solid state reaction method, are investigated. The microstructures of the samples are examined by X-ray diffractometer (XRD) as well as by Scanning Electron Microscopy (SEM). The volume fractions of the phases Bi-2223 and Bi-2212 are calculated in the bulk samples. It is observed that the c-lattice parameters increase from 30.9855Å to 31.7649Å for Bi-2212 phase whereas for the Bi-2223 phase it increases from 37.4131Å to 38.9023Å with the increasing sintering time. Meanwhile, the a-lattice parameters increase from 5.3032Å to 5.3272Å for Bi-2223 phase with the increasing sintering time. In effect, the SEM analyses of the samples indicate that the respective microstructure improves with the increasing sintering time.
