• Synthesis of YBa₂Cu₃O_7−<i>x</i>from a soluble Y‐Ba‐Cu precursor

  The synthesis of the superconducting YBa2Cu3O7−x from a soluble, molecular precursor with the composition Cu3O3Ba2Y(meOEt)7 (meOEt is 2‐methoxyethoxide) is described. The precursor was synthesized from the reaction of a soluble copper (II) oxide polymer with alkoxides of barium and yttrium. Pyrolysis and oxidation of the precursor resulted in the formation of oriented sheets of the orthorhombic YBa2Cu3O7−x

  In the development of coated superconductors sol-gel technique has been widely used as an effective processing method, especially in making long-length wires and tapes. However, one drawback associated with the deposition of YBa2Cu3O7-x and Gd2O3 buffer layer on Ni tape is the adhesion characteristic at interfaces YBCO-Gd2O3 and Gd2O3-NiO and NiO-Ni substrate. In this paper, two strategies for adhesion enhancement of multilayered ceramic oxide coatings on Ni substrate were proposed: (1) formation of chemical bonds through surface condensation reactions, and development of ceramic networks through diffusion of alkoxide precursors. The current research has focused on the fabrication and adhesion of YBCO coatings on buffered Ni substrate using nine solutions prepared from Y, Ba and Cu alkoxides, solvent and chelating agent. Only two of YBCO solutions were successfully obtained while the rest of them were unsuccessful. Among these solutions we scrutinized chemical reaction mechanisms of a successful and an unsuccessful solution for comparison. How the. chemical bonds and solubility were affected by the acids, base and solvents used in the solutions was demonstrated. It was shown that pH of the solution, homogeneity of the solution and gelation, steric affect of the chemicals in sol-gel solutions are significant issues to obtain high quality superconducting YBCO thin films. In addition, X-ray diffraction (XRD) was used to analyze phase structure of YBCO and compare results of chemical reactions obtained by a chemdraw programme. Scanning electron microscope (SEM) studies was carried out to examine microstructures of YBCO films produced from alkoxide precursors, solvent, chelating agent and modifying liquid chemical materials such as triethanolamine or ammonium hydroxide. It was found to be YBCO, Gd2O3, NiO and Ni phases in YBCO/Gd2O3/Ni sample from XRD analysis. That the solution prepared by using triethanolamine provided the best film quality and adhesion was determined by chemical reactions and gelation behaviour in the solutions and SEM observations.

  AbstractUpon reaction of titanium propoxide and yttrium 2‐methoxyethoxide with a sevenfold excess of methacrylic acid, three different mixed‐metal clusters were obtained, depending on the titanium to yttrium alkoxide ratio. Clusters of the type Ti4Y2(μ3‐O)4(μ2‐methacrylate)12(μ1‐methacrylate)2L2 (L = MeOCH2CH2OH or methacrylic acid), with two [TiO6] octahedra condensed to a zigzag chain of two [YO8] dodecahedra and two [TiO6] octahedra, were formed when the Ti/Y ratio in the precursor mixture was ⩾ 3.5. The structure of Ti4Y2O4(OMc)12(OCH2CH2OMe)2(McOH)2 obtained with a Ti/Y ratio of 2 in the precursor mixture, consists of a ring of four corner‐sharing [TiO6] octahedra to which two [YO8] dodecahedra are condensed.
