Title:
SUPERCONDUCTING MATERIAL AND PRODUCTION THEREOF
Document Type and Number:
Japanese Patent JPH01153536
Kind Code:
A
Abstract:
PURPOSE:To obtain a superconducting material useful in the field of superconductivity, having stability and productivity in a large amount, by grinding of oxides of La, Ba, Cu, etc., blending so as to make a specific composition, heating, pressurizing and molding. CONSTITUTION:Oxides of metals having a composition shown by the formula (A is one or more metals selected from a group consisting of Y, La, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er and Yb; B is one or more metals selected from the group consisting of Ba, Sr and Ca; C is one or more selected from the group consisting of Cu, Pd and Rh, not including Cu alone) are ground and blended in the composition ratio of the metals of the component A:B:C of 1:2:3 to give a mixture. The mixture is further dispersed highly, heated, pressurized and molded in a desired shape to yield a superconducting material having the composition shown by the formula.
