ABSTRACT:
Compositions having the nominal formulain-line-formulae description="In-line Formulae" end="lead"?BiaSrbCacCu3Oxin-line-formulae description="In-line Formulae" end="tail"?wherein a is from about 1 to 3,b is from about ⅜ to 4,c is from about {fraction (3/16)} to 2,x=(1.5 a+b+c+y) wherey is from about 2 to 5, with the provisothat “b+c” is from about {fraction (3/2)} to 5, containing a metal oxide phase of the formula Bi2Sr3−zCazCu2O8+wwherein z is from about 0.1 to 0.9w is greater than zero but less than 1, are superconducting. Processes for manufacturing such compositions and for using them are disclosed.
