Abstract
1245339 Super-conductors SIEMENS AG 3 Sept 1969 [4 Sept 1968] 43694/69 Headings H1A A5 and A4D A super-conductor comprises a layer of Nb 3 Sn containing C on a support. The layer is deposited on a strip-form support 12 in the apparatus shown by passing Cl 2 gas over heated sources 5 and 7 of Nb and Sn to produce NbCl 4 and SnCl 4 respectively which are mixed in tube 25 and reacted with H 2 entering through tube 17 at the surface of substrate 12 which is heated by passing an electric current through it. CCl 4 from source 22 is also added to the atmosphere surrounding substrate 12 to incorporate 0À25 to 1À3 wt per cent C in the deposited Nb 3 Sn layer. It is stated that the C may form a finely divided precipitate in the layer or may possibly form a NbC precipitate. The substrate may be a strip, wire or hollow cylinder of a metal alloy or may be quartz or ceramic. The C may also be introduced in the form of CO and the Nb and Sn chlorides may be replaced by the corresponding bromides or iodides. Gaseous HCl may be added to the H 2 flow to reduce deposition on the walls of the furnace. The C content increases the critical current (jc) of the layer and hence the H.jc product.
