Abstract
PURPOSE:To obtain a superconductive coil with a high mechanical strength by forming a coil pattern-shaped groove on a metal base, and thermally treating the base in the oxygen atmosphere by filling a predetermined compound powder in the groove after oxidizing the surface of the groove. CONSTITUTION:A spiral-shaped groove 2 is formed on a metal base 1. Copper which forms the base 1 should be a pure copper such as tough pitch copper, oxygen-free copper, or copper containing silver. A copper oxide layer 3 is formed on the surface of the side where the groove 2 of the base 1 is formed by treatments such as anodic oxidation and chemical oxidation. Cupric oxide is preferred for the copper oxide layer. Then a mixture 4 consisting of compound powders of both group IIA and group IIIA elements in the periodic table is filled. After this, by thermally treating in the oxygen atmosphere, the mixture 4 within the groove 2 is fired, while further causing the mixture 4 to react with the copper oxide layer 3 and oxygen in the atmosphere to form a superconductive layer 5 of A-B-Cu-O (where A is a group IIA element and B is a group IIIA element in the periodic table) in the interior of the groove 2, whereby a superconducting coil 6 having a spiral pattern is obtained.
