PURPOSE:To obtain a lengthy sintered body with the excellent characteristic and high critical temperature relatively easily by cutting off the slurry for the superconducting ceramic material into tapes with a slitter, baking them in the oxidizing atmosphere, and continuously winding them utilizing the plasticity at the high temperature. CONSTITUTION:The superconducting oxide powder, an organic binder plasticizer for molding, and an organic solvent are uniformly mixed to form slurry 1, and it is molded into a thin sheet by the doctor blade method. This sheet 5 is then cut off into thin tapes with a slitter 6, the tapes are put into a baking furnace 7 kept at the oxidizing atmosphere and baked at the preset baking temperature, these sintered bodies are wound within the plasticizing temperature range, thus linear lengthy ceramic sintered bodies are formed. Fine tape-shaped moldings to be sintered can be thereby kept at the desired baking temperature in the baking atmosphere, and lengthy linear sintered bodies with the excellent characteristic and high critical temperature can be easily manufactured. |
