Abstract

PURPOSE: To provide a high temperature superconductor having improved superconductivity at a high temperature by compounding at least one kind of Pb, Sn, K, Sc, etc., as adhesive element, at least one kind of La, Y, Bi, etc., as peritectic element and least one kind of Na, K, Sc, etc., as super-conductive phenomenon-accelerating element.
CONSTITUTION: The powder of raw materials comprising at least one kind of Pb, Sn, F, Br and Cl as adhesive element, the powder of raw materials comprising La, Y, other lanthanide element, Bi, Tl and Cu as peritectic element and the powder of a raw material comprising Na, K, Sc, Se, Te, Ba, Sr, Ca and Ce as superconductivity phenomenon-accelerating element are homogeneously mixed with each other in a prescribed weight ratio, placed in a biscuit tray for high temperatures, calcined at approximately 800°C in air, mixed with water and subsequently press-molded. The calcination product is fired at approximately 850°C in an inert gas atmosphere such as Ar to prepare the high temperature superconductor.
