METHOD FOR PRODUCING SURFACE LAYER OF ORIENTED CRYSTAL FROM CERAMIC HIGH- TEMPERATURE SUPERCONDUCTING MATERIAL
Process for the production of a polycrystalline, crystal-oriented layer of a high temperature superconductor of the class (Y,RE) Ba2Cu3O APPROX 7 on a substrate or between two substrates of Ag or an Ag alloy containing up to 20% by weight Au, Pd or Pt, wherein a first powder layer, of at most 5 mu m...

| description | Process for the production of a polycrystalline, crystal-oriented layer of a high temperature superconductor of the class (Y,RE) Ba2Cu3O APPROX 7 on a substrate or between two substrates of Ag or an Ag alloy containing up to 20% by weight Au, Pd or Pt, wherein a first powder layer, of at most 5 mu m thickness and consisting of the simple oxides and/or mixed oxides of the elements Y, Ba, Cu in the ratio Y:Ba:Cu:O=1:2:3:6.5, is first applied, and on it is applied a second powder layer of the superconducting substance (Y,RE) Ba2Cu3O APPROX 7 in a thickness of 5-10 mu m, and the whole is sintered in an O2-containing atmosphere. |
