Manufacture of tape-shaped oxide superconductor wire rod

Abstract

Abstract PURPOSE:To remarkably improve the critical current density by applying the process to coat an oxide superconducting viscous raw material manufactured by the sol method on the surface of a tape-shaped metal substrate. CONSTITUTION:An oxide superconducting viscous raw material manufactured by the sol method is coated on the surface of a tape-shaped metal substrate, it is baked to manufacture an oxide superconducting film on the surface of the tape-shaped metal substrate, it is pressed and heat-treated, the tape is folded along its longitudinal direction, and the oxide superconducting films are brought into contact with each other and pressed and heat-treated. A pipe-shaped metal substrate may be used in place of the tape-shaped metal substrated, the above oxide superconducting viscous raw material is coated on the inner face of the pipe-shaped metal substrated, it is baked to manufacture an oxide superconducting film on the inner face of the pipe-shaped metal substrate, oxide superconductor powder is filled in the pipe-shaped metal substrate, then processes similar to the above such as pressing and heat-treatment can be applied.
