摘要： A device for the high pressure densification of superconducting wire from compacted superconductor material or superconductor precursor powder particles, has four hard metal anvils (5, 6, 7, 8) with a total length (L2) parallel to the superconducting wire, the hard metal anvils borne in external independent pressure blocks (9, 10, 11), which are in turn either fixed or connected to high pressure devices, preferably hydraulic presses. At least one of the hard metal anvils is a free moving anvil (6) having clearances of at least 0.01 mm up to 0.2 mm towards the neighboring hard metal anvils (5, 8), so that no wall friction occurs between the free moving anvil and the neighboring anvils. This allows for high critical current densities Jc at reduced pressure applied to the hard metal anvils.

摘要： This is a method for preparing submicron-superconducting particles for use in forming a ductile superconductor wire from brittle superconducting compounds. The method utilizes preparing a mixture of solid metal halides containing essentially stoichiometric proportions of metallic components for the desired superconducting compound, co-reducing the mixture with an excess of liquid alkali metal, removing the alkali metal halide produced and the excess alkali metal from the superconducting powder, and annealing the superconducting powder to substantially remove absorbed hydrogen as indicated by the reduction of lattice parameters to essentially nominal values.

摘要： A superconductor manufacturing process provides electrical insulation and enhanced transverse electrical resistivity of multifilament superconductor strands based on Nb.sub.3 Sn. The process includes forming, during the early manufacturing steps in which the product is relatively short and of large cross section, resistive barriers around bundles of filaments in an oxide powder doped with conductive materials. In subsequent steps, an electrically insulative powder is used to insulate between a copper tube surrounding the bundles of filaments and an outer resistive ring or to insulate around multifilament strands.

摘要： A method for producing a superconductive wire, whereby an elongated intermediate element is formed out of an initial element in a deformation step and whereby the superconductive filaments are formed by a final reaction heat treatment, is characterized in that prior to the final reaction heat treatment the filaments in the intermediate element are densified in one or more high pressure densification steps following up the deformation step, said densification steps comprising a simultaneous action of at least four hard surfaces perpendicular to the axis of the elongated intermediate element, building up high pressure P≧100 MPa on a part of the intermediate element having an axial length L. This leads to a substantial increase of the critical current density Jc, whereby the anisotropy factor Γ is be almost not affected thus enabling production of almost isotropic wires or tapes.

摘要： To provide a ring crystalline body, which is a ring crystalline body with a small diameter and formed with a thin line and capable of providing electric conduction along the ring, and to provide a production method of the ring crystalline body. A droplet is stuck to a surface of a substrate and then the droplet is evaporated to a discontinuous underlayer ring having an ultrafine three-dimensional structure on the substrate surface. After that, when a transition metal dichalcogenide, a transition metal trichalcogenide, or a low-dimensional conductor as raw material gas is evaporated, a ring crystalline body comprising the raw material is grown along the underlayer ring.

摘要： This invention relates to the manufacture of Chevrel compounds by sintering a mixture of metal sulfides, metallic molybdenum and molybdenum sulfides under reduced pressure or in a stream of an inert gas containing a reductive gas, and by sintering a mixture of metal sulfides and molybdenum sulfides in a stream of an inert gas containing a reductive gas. This process does not meet any complicated procedure as in prior art and enables one to use a reaction container a desired number of times and to prepare Chevrel compounds inexpensively in large amounts.

摘要： The invention relates to a process for producing a superconducting wire, using, e.g., Chevrel phases as superconductors, in particular PbMo.sub.6 S.sub.8. Until now, it was not possible to produce superconducting wires from such materials in a technically usable quality. According to the process of the invention, the superconducting Chevrel phase is loaded vacuum-tight into a molybdenum shell and the unit is advantageously sealed in another jacket made of steel. The powdery superconducting phase has an average grain size of less than 1 .mu.m. For shaping the superconducting wire, the unit is extruded in a first process step at temperatures between 1000.degree. and 1600.degree. C. and reduced in cross section in excess of 1:10, and subsequently further treated in a plurality of process steps by additional extruding and/or hot drawing. Superconducting wires produced as specified above exhibit values for the critical quantities such as current bearing capacity, critical current density and limit values of the magnetic field that conform to those of the technically sophisticated superconductors of type II, or surpass the values of the latter type in individual instances. At the same time, it was possible to wind such wires to form coils without impairing the superconducting values due to the brittleness of the Chevrel phases.
