The present invention discloses a method for preparing a Bi-2212 HTS wire / strip, the method is: a prepared evacuation plug; Second, powder loading tube; three, the wallet in the vertical tubular sleeve furnace heating insulation; Fourth, the open end of the suction mount plug wallet sets...
All of these concerns are very much reduced in the Bi-2212 magnets described here, even though they were quenched at a new record, high wire current densityJEof up to 1000 A/mm2. Greatly assisting this performance is the use of a rather uniform, isotropic, multifilamentary HTS Bi-2212 ...
materials are fabricated into multi-filamentary wires via powder-in-tube (PIT) method followed by proper heat treatment to obtain superconductivity, but how to predict the large compression deformation behaviors of the Bi-2212 powder is critical to design the processing of the Bi-2212 HTS wire. ...

Influence of the Oxygen Partial Pressure on the Phase Evolution During Bi-2212 Wire Melt Processing We have studied the influence of the oxygen partial pressure pO2 up to 5.5 bar on the phase changes that occur during the melt processing of a state-of-the... C Scheuerlein,J Andrieux,M ...
With more than 25 years of experience in the field of High Temperature Superconducting wires (HTS), our interdisciplinary teams are working on new high tech solutions for tomorrow’s challenges. Our focus is HTS wire solutions for ultra high field applications, enabling new insights in research as...
HTS wire ends. HTS materials are brittle oxide ceramics, so they cannot be plastically deformed together to make joints without fracture of the filaments leading into the joints. Additionally, the individual HTS crystals, or “grains” comprising the superconducting pathways in a wire or tape must...
For applications requiring a Rutherford cable with a core such as NiCr, we found that a plasma sprayed ZrO 2 film was most effective in preventing "poisoning" elements present in the core from diffusing into and poisoning the HTS wire. Rutherford cable made with this wire and a thin NiCr, ...
Bi-2212CICCTorsional strainCritical currentMagnetic field intensityAs the only high-temperature superconductor (HTS) that can be made into round wire without anisotropy, Bi-2212 round wire holds significant potential for applications as CICC (cable in conduit conductor) for superconducting magnets in ...
PURPOSE: A bonding method of Bi-2212 high temperature superconductive wire is provided to zero bonding resistance by forming a superconductive junction to a bonding part of a superconductive wire. CONSTITUTION: A superconductive wire(10) comprises a superconductive filament(11) and a metal stabilizer(...
