SUPERCONDUCTING OXIDE MATERIAL AND METHOD OF OBTAINING IT

摘要

The method relates to obtaining superconducting materials, in particular, compounds of formula (I) where Y = 6-8, Ln is Y, -Sc or a lanthanoid; M is Ba, Ca, Sr; M is Cu; Cu + Ag, or of formula (II) where x = 1-2 and consists in a local initiation of an exothermic reaction in a mixture of initial components chosen so as to obtain the above-mentioned compounds. The exothermic mixture of components consists of an incombustible component and an igniting component, the latter comprising: at least one metal chosen from the group: a rare-earth metal of the periodic system from the following: scandium, yttrium, lanthanoids, a metal of the second group of the periodic system, a metal of the first group of the periodic system and/or a hydride of at least one of the metals mentioned.
