摘要:
There is described a method of applying insulative coating on high temperature superconductors and low temperature superconductors from sol-gel solutions prepared from Zr or Zr with one of, Mg, Y, Ce, In and Sn based precursor materials. The solution is prepared with isopropanol as a solvent and acetyl acetone as a catalyst. The conductors are dipped into the solution and thereafter dried at a temperature effective to evaporate the solvent. Thereafter, heat treatment in the presence of oxygen is applied at a temperature sufficient to oxidize the precursors to result in a ceramic insulative coating on the conductor.

摘要:
A process for manufacturing superconducting magnets is described. Two conducting tapes are assembled with an insulating ceramic layer deposited between facing sides of the tapes. The tapes and the insulative refractory material are bonded together by, for example, rolling to result in a self insulating substrate tape to which superconducting composition precursors are applied for later annealing. In one aspect, the composite tape is then wound to result in a pancake coil which is exposed to high temperatures in an oxidizing environment to convert the superconducting precursors to superconducting materials. The resultant high temperature superconducting composition coil can then be used as a high temperature superconducting magnet with appropriate conducting connectors applied thereto.
