    摘要： The invention concerns a method for the manufacture of a superconductor with a layer of the A-15 phase of the system Nb-Al-Si. According to the invention, a niobium carrier is provided with a layer about 0.5 to 5 .mu.m thick consisting of Nb.sub.3 (Al,Si), aluminum and silicon by placing it in an aluminum melt which contains up to 10 atomic percent of silicon and a small amount of niobium and is heated to 850.degree. to 1300.degree. C, and then the niobium carrier provided with this layer is annealed in an inert atmosphere for at least 0.5 seconds to form the layer of the A-15 phase.

    摘要： Composite billets that function as starting stock for superconducting wire are produced by immersing an assembly of rods of a superconductor alloy or rods of a metal which is capable of forming a superconductor into a molten bath of normal material, thereby encasing the assembly within normal material, allowing the molten bath to solidify and form a rough as-cast billet and thereafter zone-melting the billet so as to remove all vestiges of shrinkage cracks, surface imperfections and internal inhomogeneities.

    摘要： According to one aspect of the invention a method is provided for forming a superconductor composite. A salt is heated to a melting temperature of the salt. Superconductor particles are added to the salt. A metal composition is added to the salt. The metal composition is decomposed into a metal substance and another substance. The metal substance plates out onto surfaces of the superconductor particles to form metal plated particles. The metal plated superconductor particles are removed from the salt.

    摘要： A method is provided for fabrication of superconducting oxides and superconducting oxide composites and for joining superconductors to other materials. A coating of a molten alloy containing the metallic elements of the oxide is applied to a substrate surface and oxidized to form the superconducting oxide. A material can be contacted to the molten alloy which is subsequently oxidized joining the material to the resulting superconducting oxide coating. Substrates of varied composition and shape can be coated or joined by this method.

    摘要： The invention provides a method for forming deposits of superconducting ceramics by sequentially electrodepositing layers of metals, of a type and in proportion suitable for forming a superconducting ceramic, to form a precursor metal deposit, followed by oxidizing the precursor deposit to form a superconducting ceramic deposit. Optionally, the electroplating steps are conducted in such a manner that a patterned precursor deposit results, to obtain a patterned superconducting deposit after oxidation.
