Making a superconductive tube
Patent
·
OSTI ID:5433261
The method of U.S. Pat. No. 3,866,315 is improved by brushing copper particles also on the other side of of the niobium ribbon prior to, e.g. rolling and by increasing the layer's thickness by an electrolytic process. That layer will be on the outside of the tube. Tin is subsequently deposited thereon; and by means of annealing, the tin is caused to diffuse through this outside copper layer and into the niobium to form a uniform Nb/sub 3/Sn layer.
