Claims (6)

1. Способ изготовления сверхпроводящей проволоки конечной длины, предусматривающий, по меньшей мере, ввод исходного сверхпроводящего материала в металлическую трубку, укладывание или свертывание металлической трубки таким образом, что первая часть наружной поверхности трубки соприкасается со второй частью этой поверхности трубки, нагрев металлической трубки, заполненной исходным сверхпроводящим материалом, до температуры, близкой к точке плавления металлической трубки, для того, чтобы сформировать в исходном материале сверхпроводящую фазу, отличающийся тем, что перед укладыванием или свертыванием металлической трубки, по меньшей мере, на первую и вторую части ее наружной поверхности наносят жидкое покрытие, при этом указанное покрытие содержит по существу жидкий компонент, который полностью испаряется или выгорает при температуре, при которой происходит формирование сверхпроводящей фазы в сверхпроводящем материале, и порошковый материал, суспензированный в жидком компоненте и имеющий температуру плавления, превышающую температуру плавления металлической трубки.1. A method of manufacturing a superconducting wire of finite length, comprising at least introducing a source of superconducting material into a metal tube, laying or rolling up the metal tube so that the first part of the outer surface of the tube is in contact with the second part of this surface of the tube, heating the metal tube filled with a starting superconducting material, to a temperature close to the melting point of the metal tube, in order to form superconducting in the starting material phase, characterized in that before laying or rolling the metal tube, at least the first and second parts of its outer surface are coated with a liquid coating, said coating containing a substantially liquid component that completely vaporizes or burns out at a temperature at which a superconducting phase is formed in the superconducting material, and a powder material suspended in the liquid component and having a melting point exceeding the melting temperature of the metal pipe ki. 2. Способ по п.1, отличающийся тем, что в качестве порошкового материала используют порошкообразный оксид металла. 2. The method according to claim 1, characterized in that the powder material is used as a powdered metal oxide. 3. Способ по п.2, отличающийся тем, что порошкообразный оксид металла суспензируют с концентрацией, при которой отдельные частицы оксида металла, будучи нанесенными на первую и вторую части наружной поверхности металлической трубки, располагаются с такой плотностью, что частицы оксида металла на первой части наружной поверхности металлической трубки не соприкасаются со второй частью наружной поверхности металлической трубки, и наоборот. 3. The method according to claim 2, characterized in that the powdered metal oxide is suspended with a concentration at which individual particles of the metal oxide, being deposited on the first and second parts of the outer surface of the metal tube, are arranged with such a density that the particles of metal oxide on the first part the outer surface of the metal tube does not come into contact with the second part of the outer surface of the metal tube, and vice versa. 4. Способ по п.2, отличающийся тем, что жидкая среда, в которой суспензируется порошкообразный оксид металла, содержит растворитель, такой как ацетон, спирт или толуол, смешанный с некоторым количеством полимера, такого как поливинилбутираль (ПВБ). 4. The method according to claim 2, characterized in that the liquid medium in which the powdered metal oxide is suspended contains a solvent, such as acetone, alcohol or toluene, mixed with some polymer, such as polyvinyl butyral (PVB). 5. Способ по п.4, отличающийся тем, что поливинилбутираль добавляют в качестве полимера в количестве 0,1-10 вес.%, предпочтительно 1-4 вес.%. 5. The method according to claim 4, characterized in that the polyvinyl butyral is added as a polymer in an amount of 0.1-10 wt.%, Preferably 1-4 wt.%. 6. Способ по любому из пп.2-5, отличающийся тем, что в качестве оксида металла используют, по меньшей мере, оксид циркония. 6. The method according to any one of claims 2 to 5, characterized in that at least zirconium oxide is used as the metal oxide.
