摘要：
Compositions having the nominal formulaTl.sub.e Pb.sub.a Ca.sub.b Sr.sub.c Cu.sub.d O.sub.xwhereina is from about 1/10 to 3/2,b is from about 1 to 4,c is from about 1 to 3d is from about 1 to 5e is from about 3/10 to 1x=(a+b+c+d+e+y)wherey is from about 1/2 to 3,are superconducting. Processes for manufacturing such compositions and for using them are disclosed.
