ABSTRACT:
Vanadium-containing superconducting oxides are disclosed having critical temperature (T.sub.c) values of above about 100.degree. K. and preferably about 110.degree.-150.degree. K., together with predicted current density (J.sub.c) values on the order of 10.sup.4 -10.sup.5 amperes/cm.sup.2. The oxides hereof are moreover relatively ductile and easily bulk sintered to give end products having desirable superconductivity characteristics. Certain preferred oxides of the invention are defined by the general formula:
