Elongate Bi-based superconductors made by freeze dried conducting powders
摘要：
A superconducting tape or wire with a longitudinally extending outer layer of Ag or its alloys defining an inner region, an area of Ag or its alloys in said inner region extending longitudinally of said tape or wire separated from said outer layer of metal by freeze dried superconducting material. The inner Ag area may be a rod, a tube or a number of wires. The superconductor material is preferably B-2223.
摘要（中）：

一种超导带或线，其具有纵向延伸的Ag外层或其合金限定内部区域，所述内部区域中的Ag或其合金的区域通过冷冻干燥的超导而与所述外层金属层纵向延伸。 材料。 内部Ag区域可以是杆，管或多根电线。 超导体材料优选为B-2223。
