GONZALEZ G., J. C., OSORIO A., Ana M., BUSTAMANTE D., Ángel et al. Monitoreo de la síntesis del YBa₂Cu₃O₇ mediante la difracción de rayos X en polvo. Rev. Soc. Quím. Perú, out./dic. 2011, vol.77, no.4, p.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.
