Abstract
A process for production of superconductor wire having multiple rings, comprising the steps of: preparing a silver mixture comprising a silver or silver-gold alloy mixed with a bonding agent, and a superconductor mixture comprising a superconductor powder with bonding agent; arranging both the silver mixture and the superconductor mixture in a extrusion die; extruding a wire having at least one ring of the superconductor mixture and one ring of the silver mixture in the radial direction; and heating the wire at the sinter temperature of the oxide superconductor so that the bonding agent is removed and the oxide superconductor powder and the silver powder are sintered. A superconductor wire comprising an inner core and an outer ring covering the core, wherein one of the ring on the core comprises a sintered silver powder and the other of the ring on the core comprises a sintered oxide superconductor powder.
