ABSTRACT:
A high temperature superconductor composite material, which is suitable for production of filaments, wires, coils and other shaped products, has a ceramic powder of a material selected from the group consisting of, for example, YBa.sub.2 Cu.sub.3 O.sub.7-x and Bi.sub.2 Sr.sub.2 Ca.sub.2 Cu.sub.3 O.sub.10 ; a solution of a material selected from the group consisting of rubber silicone or lacquer silicone in a substance selected from the group consisting of toluene or acetone; and an ultra-fine silver powder dope, and is produced by using an emulsion mixture of the three major components with ultrasonic homogenization of the mixture, primer cladding of a glue-exterior layer on a silver core filament, high temperature superconductor coating of the silver core by chemical adhesion, and polymerization of the coating applied by low temperature heating, whereafter the composition is treated by magnetic treatment, gamma irradiation, and microwave supported fast heating.
