摘要: The present invention provides a method to prepare (Bi,Pb)SrCaCuO-2223 superconducting wire with improved critical current density at reduced cost. In general, the basic according comprises steps of: (a) preparing starting precursor powder oxygen content adjusted value of final 2223 phase; (b) filling into metal sheath; (c) performing deformation processing on sheath form composite and develop texture in 2212 phases; (d) sealing said so that fixed is maintained; (e) sintering obtain phase. uses metals other than silver-based material material, thus significantly reducing materials cost wire.
