METHOD FOR CRUCIBLELESS PRODUCTION OF MONOCRYSTALS Russian patent published in 1995 - IPC

Abstract RU 2038430 C1

FIELD: metallurgy of high-temperature superconductors. SUBSTANCE: crucibleless production of monocrystals YBa2Cu3O7-δ is effected with application of diffusion pairs containing: mixture of Y2BaCuO5+Ba3Cu5O8-δ mixture Y2BaCuO5+xBa3Cu5O8-δ ,, where x ∈ 1,0-1,3,. In this event, direct synthesis of superconducting compound takes place from liquid phase L and solid Y2BaCuO5 according to summary perotectical transformation Y2BaCuO5+L_→ YBa2Cu3O7-δ.. EFFECT: increased linear dimensions of monocrystals and higher yield percentage. 3 dwg, 1 tbl
