    摘要: Processes for economical large scale commercial production of blocks of quantum well particles, platelets, or continuous sheets of material imparting minimal or essentially no parasitic substrate loss in quantum well devices such as thermoelectric generators in which the blocks are embodied involve roll to roll processing, i.e., deposition and crystallization of alternating layers of quantum well materials, on an elongate and continuous base layer of appreciable width. Blocks of quantum well materials having no attached base layer are produced on decomposable or release treated base layers.

    摘要: An aqueous and method for manufacturing a ceramic superconductor coated metal fiber comprises a container for holding a nonaqueous solution inwhich particles of superconductor material are colloidally suspended to form a slurry. A voltage source is provided to influence the slurry with an electric field and a magnet device is provided to influence the slurry with a magnetic field. The magnetic field is oriented relative to the fiber to align the superconductor particles of the slurry in a desired orientation for subsequent attachment onto the surface of the fiber. The voltage source is connected to the metal fiber to electrically bias the fiber as it is drawn through the slurry. Consequently, charged superconductor particles in the slurry attach to the electrically biased fiber. Subsequently, the coated fiber is heated to sinter the aligned particles and establish a ceramic superconductor shell on the metallic fiber substrate.

    摘要: Heavy fermion materials are used for thermally stabilizing systems which operate below about 10.degree. K., particularly superconducting systems. These materials have extremely high heat capacities below 10.degree. K., and furthermore, their heat capacities are substantially unaffected by magnetic field intensity, making them especially useful for thermally stabilizing superconducting magnet windings. In a particular application, a superconductor includes superconducting filaments surrounded by a metal stabilizer and heavy fermion material is incorporated in insolubilized form in the stabilizer.

    摘要: A melt processing method for bulk or thick film fabrication of RE123 superconductor material includes the steps of using Nd in the RE123 to increase the recrystallization speed of the RE123, and using a heavy rare earth in the RE123 to establish the peritectic melting point of the RE123 somewhere below the melting point of silver. Within these requirements, the method essentially includes heating the RE123 above its peritectic melting point, and then cooling the resultant decomposed material to recrystallize the RE123. The heavy rare earths to be used for lowering the RE123 peritectic melting temperature include Lu, Yb, Tm or Er or mixtures thereof. The addition of RE211, silver and the use of a low oxygen partial pressure also contribute to a lowering of the melting point of the RE123. When using Nd to accelerate the processing time, the RE123 can include a first component of Nd.sub.1-z R.sub.z 123 and a second component of Nd.sub.1-y R.sub.y 211. For these components, R is one of the heavy rare earths, z is between 0 and approximately 0.9, and y is between 0 and approximately 0.9.

    摘要: A method for heat processing a superconductor wire which has a protective silver cladding includes the steps of attaching the coated wire to a spool and then rotating the spool to wind the wire around the spool in juxtaposed coils. As the wire is being wound around the spool, the portions of the wire which are not yet coiled are drawn through a container which holds a paint that contains a silver diffusion inhibiting material. The diffusion inhibiting material is consequently deposited onto the silver cladding of the superconductor wire, and the coiled wire is subsequently placed in a furnace. The wire is heat processed in the furnace as appropriate for the particular type of superconductor material. The diffusion inhibitor material prevents diffusion of silver during the heat processing between portions of the wire which contact each other.
