Abstract
An oxide superconductor cable and a method of producing the same. The oxide superconductor cable includes a ceramic fiber and an oxide superconductor layer coated over the ceramic fiber. Such a structure of the cable provides flexibility to it to some extent and enables it to become relatively thin.
Claims9
An oxide superconductor cable comprising:
- (a) a fiber having an outer surface;
- and
- (b) an oxide superconductor layer disposed to cover the outer surface of said fiber, about 0.1 to about 5 .mu.m thick, and represented by the formula:
- A.sub.x B.sub.y Cu.sub.z O.sub.9-.delta.
- wherein:
- A includes at least one element selected from the group consisting of Sc, Y, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu;
- B includes at least one element selected from the group consisting of Be, Sr, Mg, Ca, Ba and Ra;
- 0.1.ltoreq.x .ltoreq.2.0;
- 1.ltoreq.y.ltoreq.3;
- 1.ltoreq.z.ltoreq.3;
- and 0.ltoreq..delta..ltoreq.7, wherein said fiber is made of a material selected from the group consisting of silica glass, multi-component glass, Al.sub.2 O.sub.3, TiO.sub.2, ZrO.sub.2, and YAG.
