Description

Four powder mixtures with chemical formula La1+xBa2-xCu3Oy was prepared. The mixtures were heated in free atmosphere, at temperature 850 deg. C for 60h and then at 860 deg. C for 40h. XRD measurements were obtained with CuKa radiation. The samples were characterized with the help of the PDF and refined, using the Rietveld's 'Powder Profile Analysis'. Four phases, same for all the samples, were found: (La,Ba)2CuO4, BaCuO2, LaBa2Cu3O7-d, and BaCO3. The percentages of the tour phases are changed, as the x quantity increases, and varied from 38, 25, 18, 19%, for x=0, to 69, 14, 7, 10%, for x=0.6, respectively
