Abstract

PURPOSE: To obtain a long, mechanically and electrically stable superconductive wire with high current density by forming a sintered layer of ceramic superconductive substance and a stabilizing material consisting of ceramic or highpolymer material on the periphery of a ceramic fiber strand in the sequence as named.
CONSTITUTION: A strand 11 of ceramic fibers is covered with a ceramic superconductive substance or a substance to produce it by heating in oxidative atmosphere. Then this substance is sintered, and the resultant sintered layer 12 is covered with a stabilizing material 13 consisting of conductive ceramic or conductive highpolymer material. The ceramic fiber shall preferably be of SiC type or of oxygen type, and its volume specific resistance be favorably under 105Ωcm. This allows easy formation of a long wire, wherein heat treatment in oxidative atmosphere can take place while it is long, and a practically applicable wire with strength and high critical current density can be obtained.
