IPC: B28B1/00
Filed: 1990-07-20
Abstract: PURPOSE:To manufacture efficiently an oxide superconductive conductor excellent in superconductivity by applying a second heat treatment process to a crystallized oxide superconductive conductor layer. CONSTITUTION:After a metal tube 1 filled with tentatively baked powder is given elongation processing, this elongated material is heated at a temperature T1 above the temperature, where a tentatively baked powder layer is partly melted, followed by being cooled at a speed 0.01 to 100 deg.C/min. The elongated material is crystallized by this first heat treatment process being C-axially oriented. A heating temperature T2 in a second heat treatment process is made 20 to 150 deg.C lower than heat treatment temperature T1 in the first heat treatment process. It is because, when the temperature T2 is lower than T1 by less than 20 deg.C, adjustment of crystal structure is not effected, and when T2 is lower than T1 by more than 150 deg.C, oxygen is not sufficiently performed.
