Abstract: Compositions having the formula A1 x m 2 x Cu3Oy, 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 77°K. 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°C and about 1100°C and slowly cooling the mixture to room temperature in the presence of oxygen over a period of at least four hours.

Abstract: A process for forming a composite high temperature superconductor copper wire, said process comprising the steps of (1) directing a submicron sized powder of a superconducting ceramic material through a length of copper tubing to coat the interior surface of said tubing with a uniform compact film of said powder, and (2) sintering said powder while passing oxygen through said tube and while maintaining the outside of said tube in an inert atmosphere. In a preferred embodiment an aerosol process is used to generate the submicron sized powder of the superconductor.

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: Optical printing of highly conductive lines or characters is described, wherein an organic .pi. -electron donor compound, dissolved in a halocarbon, is deposited onto a substrate. The coated substrate is exposed to actinic radiation in a predetermined pattern, and then the halocarbon is removed. The compositions used are of the type (Donor)xn where the donor is typically selected from TTF, TSeF, DSeDTF, and their substituted derivations where x may be selected from F, Br, Cl and I, and n
