Fabrication of superconductor coils
Small coils of superconducting YBa{sub 2}Cu{sub 3}O{sub 7-x}(123) can be formed in the green state using a layered superconductor/insulator tape. In this approach, the insulator prevents contact between the turns of the coil during firing. The insulator must be chemically compatible with 123 during firing, and ideally should match 123 with respect to firing shrinkage and thermal expansion. Fabrication of small coils from the layered superconductor/insulator composites 123/Y{sub 2}BaCuO{sub 5} and 123/BaCuO{sub 2} will be discussed. The issue of chemical compatibility will be addressed, and measurements of the firing shrinkage and thermal expansion will be presented for 123 and the two insulators Y{sub 2}BaCuO{sub 5} and BaCuO{sub 2}. In addition, the superconducting properties of 123 in the composites will be presented. 8 refs., 3 figs.
