GONZALEZ, J. C.  e  OSORIO, A.. Bond valence model applied to superconductor YBa₂ Cu₃ O_7-x. Rev. Soc. Quím. Perú [online]. 2008, vol.74, n.4, pp.298-310. ISSN 1810-634X.

We calculated the distance among cations and anions of the superconducting compound YBa₂Cu₃O_7-x by using the Bond Valence Wizard program. The program uses the Pauling's concept of bond valence. We compared the results obtained with YBa₂Cu₃O_7-x distances refined by Rietveld method and the distances found in the literature. The bond valence method is an useful tool in evaluating inorganic structures.

Palavras-chave : YBa₂Cu₃O_7-x superconductor; Bond valence method.
