SUPERCONDUCTING WIRE AND METHOD OF MAKING SAID WIRE Russian patent published in 2010 - IPC H01B12/00 

FIELD: chemistry.

SUBSTANCE: invention discloses a superconducting wire and a method of making said wire, according to which the superconducting wire has different types of separators placed between an anti-diffusion pipe and modules, in order to ensure uniform deformation of the modules made from a copper matrix and niobium fibre in the middle of which a rod made from copper or copper alloy is inserted. In each gap formed between modules, different types of separators are also inserted in accordance with the shape of each gap. The copper separator or separator with low content of tin relative content of copper, in which the ratio of the cross sectional area of copper to the cross sectional area of tin is greater than 6.0, is placed between three modules, as well as between two modules and the anti-diffusion pipe, and a separator with high content of tin relative content of copper, in which the ratio of the cross sectional area of copper to the cross sectional area of tin is less than 0.01-1.5, or a separator with average content of tin relative content of copper, in which the ratio of the cross sectional area of copper to the cross sectional area of tin is less than 1.5-6.0, is placed between four modules.

EFFECT: formation of high-quality superconducting material Nb3Sn, higher critical current of the superconducting wire.
