Abstract: Compositions having the formula A1+/-xM2+/-xCu3Oy, wherein A is Y, or a combination of Y La, Lu, Sc or Yb; M is Ba, or a combination of Ba, Sr or Ca and y is sufficient to satisfy the valence demands, have been found to be bulk electrical superconductors at a temperature above 77K. The compositions are single phase perovskite-like crystalline structures. They are made by a process involving intimately mixing the metal oxides or their precursors in the proper molar ratios, heating the mixture in the presence of oxygen to a temperature between about 800 DEG C and about 1100 DEG C and slowly cooling the mixture to room temperature in the presence of oxygen over a period of at least four hours.

Abstract: Stable, bulk electrical superconductors are prepared by heating mixed metal oxides in the presence of oxygen in a closed vessel in a preheated oven for 1-5 hours at 850-900 DEG C. The final oxides are in the molar ratio Tl0.6-1.1Ca2-3Ba0.75-1.25Cu2-3O(5+ delta )-(9+ delta ), where delta is less than one.

Abstract: A method of optically printing conductive characters using charge transfer compounds is provided. The method is characterized by depositing an organic pi electron donor compound dissolved in a halogenated hydrocarbon (halocarbon) on a suitable substrate and selectively exposing the so coated substrate to actinic radiation to obtain a permanent, highly conductive, image.
