AbstractThe PrBa2-xSrxCu3O7+/-delta solid solution was investigated by means of X-ray powder diffraction in combination with Rietveld analysis. The Sr-doped Pr123 single phase could be synthesized at 950degreesC in air. The solubility of PrBa2-xSrxCu3O7+/-delta solid solution is 0.2 less than or equal to x less than or equal to 0.6. The structure of PrBa2-xSrxCu3O7+/-delta is orthorhombic for x = 0.2. The structure transforms into tetragonal for 0.3 less than or equal to x less than or equal to 0.6. In the PrBa2-xSrxCu3O7+/-delta structure, Sr ions can replace Ba ions, the highest value is x = 0.6 under our experimental condition. But Sr ions could not replace Pr ions. Furthermore Pr ions could not occupy the sites of Ba ions in the PrBa2-xSrxCu3O7+/-delta system. Both ionic radii and chemical properties play an important role in the mutual substitution of Pr, Ba and Sr ions in the Pr123 structure of the PrBa2-xSrxCu3O7+/-delta system. (C) 2003 Elsevier B.V.
