Beschreibung
Zusammenfassung:FIELD: high-temperature superconducting materials synthesis. SUBSTANCE: charge of stoichiometric composition corresponding to composition of material BiSrCaCuO+δ is prepared and annealed, melted and hardened in the open air and then it is subjected to thermal treatment under temperature of 840 - 845 C at least for 10 hours. After that material has share of BI-2212 phase equal to 70 - 90 %. EFFECT: simplified process. Использование: в технологии синтеза высокотемпературных сверхпроводящих материалов. Сущность изобретения: готовят шихту стехиометрического состава, соответственно составу материалаBiSrCaCuO+δотжигают ее, расплавляют и закаливают на воздухе, после чего проводят термообработку при 840 - 845С не менее 10 ч. Свойства материала: процентное содержание фазы Bi - 2212 составляет 70 - 90%.
