SUPERCONDUCTING METAL OXIDE COMPOSITIONS AND PROCESSES FOR MANUFACTURE AND USE

摘要

Compositions having the nominal formula TlBaaCabCucOx, wherein a is from about 2 to 4, b is from about 7/2 to 5, c is from about 9/2 to 7, x = (a + b + c + y), where y is from about 1/2 to 3, are superconducting. Processes for manufacturing such compositions and for using them are disclosed.
