METHOD FOR PRODUCING THICK HIGH-TEMPERATURE SUPERCONDUCTING FILMS Russian patent published in 1997 - IPC

Abstract RU 2083032 C1

FIELD: cryoelectronics, instrumentation engineering, and production of superconducting lines noted for high critical current density. SUBSTANCE: method for producing superconducting films of YBa2Cu3O7 includes gasostatic pressing of film, upon its application to substrate, at pressure of 1800-2000 atm and temperature of 750-800 C for 30-60 min in order to produce thick film lines of high-temperature superconductor material which function to convey electric energy under cryogenic conditions without loss. EFFECT: improved film density and greatly increased current density; reduced size of electronic hardware. 2 tbl
