We report the production and cha racterization La 1.1 Ba 1.4 Ca 0.5 Cu 3 O z , La 1.1 Ba 1.5 Ca 0.4 Cu 3 O z , La 1.1 Ba 1.6 Ca 0.3 Cu 3 O z , La 1.2 Ba 1.3 Ca 0.5 Cu 3 O z , La 1.2 Ba 1.4 Ca 0.4 Cu 3 O z , La 1.3 Ba 1.2 Ca 0.5 Cu 3 O z , systems, in contrast to those reported in previous articles [2]. The material was produced by the solid state reaction method (SSR) with a sintered temperature between 820 and 850 º C. The morphological characterization with respect to the granular behavior using the Scanning Electron Microscopy (SEM) technique i s showed; the structural characterization is obtaine d submitting the specimen to X Rays Diffraction (DRX) and the structural parameters are got implementing the Rietveld refinement method in software FullProf; the material results to possess tetragonal unitary cells ty pe P 4/mmm perovskite with a ≈ 3.89 Å , b ≈ 3.89 Å and c ≈ 11.60 Å . Systems have a pure phase, single phase as proposed by West. The critical temperature is compared with the parameters x and y. 2016 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49648868014 https://www.redalyc.org/journal/496/49648868014/ https://www.redalyc.org/journal/496/49648868014/html/ https://www.redalyc.org/journal/496/49648868014/49648868014.epub https://www.redalyc.org/journal/496/49648868014/movil es http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.199 Vol.83 |
