Title:
酸化物系超電導線材の製造方法
Document Type and Number:
Japanese Patent JP2527789
Kind Code:
B2
Abstract:
PURPOSE:To form an oxide superconductor of a homogeneous crystal structure by forming a mixed material layer including each element that compose a superconductor of oxide on the surface of the base material by means of the chemical evaporation method and providing a heat treatment simultaneously with or after the formation of this material layer. CONSTITUTION:A superconductive wire rod of oxide provided with oxide superconductor of A-B-Cu-O is formed. This A indicates more than one kind of elements of periodic table group IIIa such as Y, Sc, La, Yb, Er, Eu, Ho, Dy, etc., and B indicates more than one kind of elements of periodic table group IIa such as Be, Mg, Ca, Sr, Ba, etc. A long sized base material 10 of a round liner rod is bound to a rolled roll in a vacuum container 21 of a plasma CVD device, shifted to a roll 26 on the other side and the base material shifted in the evacuated container 21 is heated by means of a heater 27. Powder 29 of BaCo3 is transferred from a supply port 28 of a plasma generating tube 22 by means of carrier gas at the time of shifting the base material 10, and at the same time, plasma flange 30 is generated toward the base material 10 of the container 21 by activating an induction heater 23.
