ABSTRACT:
A method is provided for producing polycrystalline superconductor materials which utilizes a zdense and non-polluting 211 substrate which has been pre-sintered prior to melt processing with a 123 superconducting material. The resulting melt-processed material may be fabricated into a 123 superconductor having a single crystal size of up to 60 mm long which can carry very high current of up to about 1,500 A at 1 .mu.V/cm criterion.
