Abstract
A powder in tube method of making an HTc superconductive multifilament strand having a silver-based matrix, in which method: prior to the monofilament step: a composite multilayer material is prepared comprising at least one silver-based sheet, and at least one layer of non-superconductive ceramic material that is permeable to oxygen; and during the monofilament step, a thickness of composite multilayer material is interposed between first and second thicknesses of silver-based material, thereby forming said first silver-based envelope.
