Superconducting film fabrication by the sol-gel process
A sol-gel approach based on polymerization chemistries of alkoxide precursors was used to produce yttrium barium cuprate (YBa{sub 2}Cu{sub 3}O{sub 7-x}) superconducting films. The alkoxide precursors were also synthesized at the INEL either because they were not commercially available or because the available alkoxides were not suitable for sol-gel synthesis. It has been demonstrated that the chemical homogeneity of sol-gel derived YBa{sub 2}Cu{sub 3}O{sub 7-x} is superior to that produced by the conventional solid state chemistry approach, even though both powders appeared to be single phase'' YBa{sub 2}Cu{sub 3}O{sub 7-x} by x-ray diffraction analysis. Superconducting thin films were fabricated from partially polymerized alkoxide solution on polycrystalline and single crystal substrates. The characteristics of these films have been reported. The precursor solution used for thin film fabrication produced a paste-like viscous, stable fluid which could be used as a potential material for fabricating superconducting fiber and/or wire. 17 refs., 31 figs.
