摘要:
A thin film of a compound having a large area is continuously produced on a substrate by depositing elements constituting the compound from a target member onto the surface of substrate by spattering comprising steps of: rotating a target member having a flat surface around an axis which crosses the surface and comprising elements of the compound so that a part of the surface of target member is positioned at a first spattering position and another part of the target member is positioned at a second spattering position, at the first position, spattering at least one target comprising at least one element of the compound which is easily splashed so as to supply the deficient element to the target member, and at the second position, spattering the elements from the target member so as to deposit them on the surface of said substrate with continuously supplying the substrate so that a part of the substrate is positioned in a flying line of the elements, whereby an elementary composition of the target member at the second position is adjusted at a predetermined composition.

摘要:
A continuous method for manufacturing an elongated superconducting campsite composed of a superconductor consisting of compound oxide 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 technique, heating the pre-form continuously to remove said binder, wrapping the pre-form with a metallic sheet, and then subjecting the pre-form wrapped with the metallic sheet to sintering operation to sinter said material powder.
摘要:
After-treatment of a compound oxide type superconducting material by oxygen plasma to improve the superconducting property of the material. The treatment by oxygen plasma is preferably performed while the material is heated at 500 to 1,000 °C. The material may have a form of bulky mass or of a thin film deposited on a substrate by physical vapour deposition technique.

摘要:
An alloy consisting of metal elements, such as Y, Ba and Cu which are constituent elements of a superconducting compound oxide to be produced is oxidized so that a surface of the alloy is converted to the superconducting compound oxide such as YBa₂Cu₃O 7-δ .
