Abstract
Organometallic precursors from naphthenic acid and metal nitrates were used for the synthesis of YBa2Cu3O(7-x) (so called YBCO or 123) super conducting compounds. The characteristics of metal naphthenates as org anometallic precursors were investigated by IR spectra and viscosity m easurements. 123 superconducting compound obtained from 123 naphthenat e showed a T(c) of 90-degrees-K and a rather dense and elongated micro structure. Four probe resistance measurements and carbon content deter minations were carried out to characterize superconducting properties of the samples obtained in this study.
