MANUFACTURE OF OXIDE SUPERCONDUCTIVE WIRE ROD

摘要

PURPOSE:To provide the manufacture of oxide superconductive wire rod having a high critical current density and provided with the stabilizing material on the peripheral surface thereof. CONSTITUTION:A raw wire material 1 made of the sintered body, which is composed of Bi group superconducting component, is melted locally to form a melting part 3. The melted liquid is led out from the melting part 3 through a pipe 5, and is solidified to form an oxide superconducting wire material 11 having a wire diameter of 2mm or less. Next, electroplating of Ag is applied to the peripheral surface of the oxide superconductive wire rod 11 at a current density of 0.3A/dm<2> or more.
