Ceramic sheet for heat-treating metal composite superconductive wires and methodusing the same for heat treating metal composite superconductive wires, and sup erconductive magnet and method of producing the same
A method of heat treating metal composite superconductive wires, and a method using a heat treatment ceramic sheet for producing superconductive magnets. A metal composite superconductive wire (1) composed of a single-core wire or multi-core wire of bismuth type oxide superconductive material coated with silver or a silver alloy and a heat treatment-purpose ceramic sheet (2) composed of alumina fiber and zirconia powder in a volume ratio of 9:1 to 1:9, the balance being a binder which will disappear when heat treated are put one on top of the other and wound to form a pancake-like coil, which is then heat treated.
