FIELD: production of lamellar phase having composition Sr1-xLnxCuO2 (where Ln is Pr, Nd) which may be used in power engineering, electronics, in computer and measuring technique as high temperature superconducting material having transition point into superconductor state equal or lower than 45 K. SUBSTANCE: method involves mixing or origin components followed by treatment thus prepared mixture in thermal vacuum chamber. Said mixture is placed into container whose walls are covered by layer of insulation material. Cuprites of suitable metals are used as origin components, copper foil being used as said insulation material. Duration of the process as a whole is 30-40 min. Content of superconducting phase in desired material is about 60 %. EFFECT: simplified method and decreased its cost.
