Изоб ретение относитс  к физическим методам разделени  веществ, а именно к технологии разделени  сверхпровод щих материалов.The invention relates to physical methods for the separation of substances, namely, to a technology for the separation of superconducting materials.

Известны магнитные способы разделени  смесей, содержащих ферромагнитные ле1чества, такие как Fe, NI, Co-содержащие соединени  и сплавы . Выделение ферромагнитных веществ из смесей осуществл ют под действием магнитного пол  til ГЗ.Magnetic methods are known for separating mixtures containing ferromagnetic materials, such as Fe, NI, Co-containing compounds and alloys. Extraction of ferromagnetic substances from mixtures is carried out under the action of a magnetic field til GB.

Недостатком этих способов  вл етс  невозможность разделить неферромагнитные вещества, например соединени  переходных металлов с азотом , углеродом, которые  вл ютс  сверхпроводниками.The disadvantage of these methods is the inability to separate non-ferromagnetic substances, for example, transition metal compounds with nitrogen, carbon, which are superconductors.

Известен также способ отделени  посто нного магнита от сверхпровод щего тела. Отделение магнита от сверхпроводника осуществл ют путем охлаждени  сверхпроводника, наход щегос  в поле отдел емого посто нного магнита, до температуры, ниже температуры перехода в сверхпровод щее состо ние .There is also known a method of separating a permanent magnet from a superconducting body. The magnet is separated from the superconductor by cooling the superconductor that is in the field of the separable permanent magnet to a temperature below the transition temperature to the superconducting state.

Такой способ позвол ет отделить посто нный магнит только от сверхпроводников I рода, таких как чистые металлы, например Нд, V, РЬ, Sn, Zn, но недостаточно эффективен (или невозможен) в слвчае отделени  магнита от сверхпроводников П ррда, Such a method only allows a permanent magnet to be separated from type I superconductors, such as pure metals, e.g., Nd, V, Pb, Sn, Zn, but not effective enough (or impossible) in separating the magnet from the superconductors P rrd,

10 к которым, в частности, относ тс  нитриды и карбиды переходных металлов , а также интерметаллические соединени  со структурой типа fJ-W, так как при переходе их в сверхпро15 вод щее состо ние в магнитном поле происходит замораживание магнитного потока. Кроме того, вследствие произвольного характера охлаждени  JQ системы магнит - сверхпроводник и подвижности магнита, этот метод не позвол ет раздел ть смесь сверхпроводников с различной кргитической температурой.10 to which, in particular, nitrides and carbides of transition metals, as well as intermetallic compounds with a structure of the fJ-W type, since during their transition to a superconductive state in a magnetic field, freezing of the magnetic flux occurs. In addition, due to the arbitrary nature of the JQ magnet-superconductor system and the magnet mobility, this method does not allow separating a mixture of superconductors with different crits.
