Title:

IRON-BASED COMPOUND SUPERCONDUCTIVE WIRE MATERIAL AND STRIP MATERIAL, AND PREPARING METHOD OF THE SAME

Document Type and Number:

WIPO Patent Application WO/2009/135348

Kind Code:

A1

Abstract:

Superconductive wire and strip materials are provided, whose cores are superconductive iron-based compound. Outside of the cores are covered with a metallic tube, a compound metallic tube or an alloy tube. Materials of the canning tube are chosen from iron, copper, low carbon steel, non-corrosive steel, chrome, vanadium, manganese, titanium, zirconium, molybdenum, nickel, niobium, wolfram, celtium or tantalum. Preparing method of the superconductive wire or strip material is as follows: well mixing and milling the raw material exactly prepared according to chemical formula LnO1-xFxMPn or LnOMPn (wherein Ln is one or more elements selected from the group of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y;M is one or more elements selected from the group of Fe, Co, Ni and Ru;Pn is As, P or Sb;x=0-0.50); feeding the raw material into the metallic tube; filling the raw material compactly; sealing two ends of the tube; spin-forging, drawing, and rolling the metallic tube (rolling is only for the preparation of strip material); vacuum-annealing or annealing the obtained wire or strip material in inert atmosphere.
