ABSTRACT:
Process for producing superconducting metal-oxide textiles comprising impregnating a preformed, organic textile material with metal compounds in a desired atomic ratio, heating the material in a weakly oxidizing atmosphere to pyrolize and oxidize the organic material, maintaining the material at temperature in an oxidizing atmosphere, and cooling the material in an oxidizing atmosphere, so as to form a crystalline structure capable of superconducting.
