Abstract
A powder in tube type method of making an HTc superconductive multifilament strand having a silver-based matrix, and an HTc superconductive multifilament strand having a silver-based matrix. The method includes, prior to the monofilament step, preparing a composite multilayer material is including at least one silver-based sheet, and at least one layer of non-superconductive ceramic material that is permeable to oxygen. During the monofilament step, a thickness of composite multilayer material is interposed between first and second thicknesses of silver-based material, thereby forming the first silver-based envelope.
