Title:

PROCESS FOR PRODUCING THICK-FILM TAPE-SHAPED RE-TYPE (123) SUPERCONDUCTOR

Document Type and Number:

WIPO Patent Application WO/2007/069524

Kind Code:

A1

Abstract:

This invention provides a production process of a thick-film tape-shaped RE-type (123) superconductor having a high critical current value. The production process comprises providing a composite substrate comprising Gd2Zr2O7 and CeO2 stacked in that order on a Hastelloy substrate, coating a raw material solution prepared by dissolving a trifluoroacetate of Y and Ba and a naphthenate of Cu onto the composite substrate, heat treating the coated composite substrate by calcination, then subjecting the calcined assembly to intermediate heat treatment at a temperature below the temperature of heat treatment for superconductor production, and then heat treating the assembly in an argon gas atmosphere under conditions of highest heating temperature 760ºC, water vapor partial pressure 13.5%, and oxygen partial pressure 0.09% for superconductor production to produce a tape-shaped RE-type (123) superconductor comprising a YBCO superconducting film having a thickness of more than about 2 μm.
