Abstract
A continuous method for manufacturing an elongated superconducting campsite composed of a superconductor consisting of compound oxided and a metal sheath surrounding the superconductor, including the steps of kneading a material powder of superconducting compound oxide with a binder, continuously shaping the resulting kneaded paste into an elongated pre-form by an extruder or by coating technlque, heating the pre-form continuously to remove said binder, wrapping the pre-form with a metallic sheet, and then subjecting the pre-form from wrapped with the metallic sheet to sintering operation to sinter said material powder.

A method for manufacturing an elongated superconducting composite composed of a superconductor consisting of compound oxide and a metal sheath surrounding said superconductor, including the steps kneading a material powder of superconducting compound oxide with a binder to prepare a kneaded paste, continuously shaping said kneaded paste into an elongated pre-form by a means selected from the group consisting of an extruder and a coating apparatus, heating said pre-form continuously to remove said binder, wrapping said pre-form continuously with a metallic sheet made of Ag, and then continuously subjecting said pre-form wrapped with said metallic sheet to sintering operation to sinter said material powder at a sintering temperature between 850.degree. C. and 950.degree. C.;
- said pre-form being in the form of a tape having a thickness of less than 2 mm or in the form of a wire having a diameter of less than 2 mm.
