Title:
MANUFACTURE OF SUPERCONDUCTING CERAMIC COIL
Document Type and Number:
Japanese Patent JPS6484608
Kind Code:
A
Abstract:

PURPOSE: To obtain a superconducting coil easily by a method wherein the powder paste of superconducting ceramic, having a prescribed composition, is printed, coated and sintered on the ceramic substrate having a specific composition, and the coil is manufactured.

CONSTITUTION: Paste A is manufactured using the superconducting ceramic material having the critical temperature, at which it is changed to a superconducting state, which is higher than the boiling point of liquid nitrogen. Said paste A is applied by printing on a ceramic substrate 1, it is sintered and a thick film-like superconducting coil 2 is formed. At that time, Sm2MCuO5 is used as the substrate 1, and the superconducting ceramic having the composition of LnM2Cu3O7-k is used as the paste A, provided that Ln contains at least a kind selected from the rare-earth elements of La, Nd, Pm, Sm, Eu, Gd, Dy and Ho, M contains at least a kind selected from Ba, Sr and Ga, and k is used in the form of 0<k<1. As a result, the superconducting coil 2 can be obtained easily.
