Abstract

A process for preparing a superconducting compsn. having the formula MBa2Cu3Ox where M is selected from Y, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb and Lu; x is 6.5 to 7.0; the compsn. has a superconducting temp. of about 90K. The process includes mixing M2O3, BaO2 and CuO in an atomic ratio of M:Ba:Cu of about 1:2:3; heating the mixture in O2 containing atmos; 850 to 925 deg.C for a time sufficient to form MBa2Cu3Oy, where y is 6.0 to 6.4, followed by cooling while maintaining the O2 containing atmos. until the desired product is formed. Pref. the mixture is pressed into a desired shape prior to heating.
