METHOD OF MANUFACTURE FOR SUPERCONDUCTOR COMPOUND MATERIALS

摘要

There are provided a manufacturing method of silver-high temperature superconductor wire rod. The method is comprised of calcinating in the air by using PbO, Bi2O3, SrCO3(or SrO), CaCO3(or CaO), CuO powder, whereby making a lump which superconductor(Bi,Pb)2Sr2Ca2Cu3O8 is mixed with the second phase, shaping this powder in a mold, locating it inside of silver powder, making composite of silver powder and superconductor shaped body with the completed form of mold, proceeding, intermediate annealing, and final annealing the annealed complex form body of silver-superconductor through the rolling, drawing or extrusion.
