ABSTRACT:
A superconducting oxide wire and a method of manufacturing the same are disclosed. The wire comprises a pipe made of a metal and a superconducting oxide material filling the interior of the pipe and comprising superconducting oxide grains which are bonded to each other and which have a perovskite crystal structure having a C face and a C axis. The superconducting oxide grains contain more than 50 vol % of plate-shaped grains of which the length in the direction of the C face is greater than the length in the direction of the C axis. The C faces of most the plate-shaped grains are arranged to be directed toward longitudinal axis of the pipe.
