| 简介 |
PROBLEM TO BE SOLVED : PLD by cracking is hard to occur in the film forming process, superconducting properties, and, a uniform quality and superconducting properties of the thin oxide superconductor thin film can be formed using the same manufacturing target and of an oxide superconducting wire material and manufacturing method. SOLUTION : the present invention of a target for producing thin superconductor, REBa 2 cu 3 O x (RE of rare earth element selected from the elements in 1) represented by the sintered body contains a rare earth oxide superconductor, RE compd., Ba compd., cu compd. raw material powder is calcined to obtain a calcined body and the calcining process, the calcined body by crushing and grinding process to obtain a powder, the powder is compacted and process to obtain a pressed powder compacting, sintering the green compact to obtain a sintered body and the firing process, which is manufactured by, 50-72% and a relative density of theoretical density.
