GONZALEZ G., J. C.; OSORIO A., Ana M.; BUSTAMANTE D., Ángel y BEJAR R., Manuel. Monitoring of the YBa2Cu3O7 synthesis by X- ray powder diffraction. Rev. Soc. Quím. Perú [online]. 2011, vol.77, n.4, pp.249-258. ISSN 1810-634X.
We study the formation dynamics of the YBa2Cu3O7 superconducting phase, from Y, Ba and Cu acetates prepared by the Sol-Gel method. The monitoring is done through by Rietveld refinement of the X-ray powder diffractograms at the end product resulting in three specific stages of the thermal treatment: (a) precursor, (b) calcined and (c) sinterized.
