<p>Compositions having the nominal formula Tle Pba Cab Src Cud Ox wherein a is from about 1/10 to 3/2, b is from about 1 to 4, c is from about 1 to 3, d is from about 1 to 5, e is from about 3/10 to 1, x = (a + b + c + d + e + y) where y is from about 1/2 to 3, are superconducting. Processes for manufacturing such compositions and for using them are disclosed.</p> |
