Title:
METHOD OF FORMING SUPERCONDUCTIVE LAYER ON TUBULAR CONDUCTOR
Document Type and Number:
Japanese Patent JPS54108594
Kind Code:
A
Abstract:
A super conductor is made by first shaping a copper strip carrying a niobium layer into a corrugated tube; thereafter tin is deposited on the tube which is coiled, hung from a ceramic rod and placed into an annealing furnace being evacuated thereafter, the interior of the tube is sealed off from the interior of the furnace. After, e.g. two hours of heating for causing the tin to diffuse into the niobium, a sufficiently thick layer of Nb3Sn has developed and a cold inert gas is flushed through the tube to rapidly cool the tube while retaining it in the evacuated but no longer heated furnace.
