Abstract
SmBa2Cu3O7-y (Sm123) seeds dissolved partly or completely during top-seeded melt growth (TSMG) processing of YBa2Cu3O7-y. It made a solid solution of (Y1-xSmx)Ba2Cu3O7-y and (Y1-xSmx)(2)BaCuO5 around the seed/compact interfac es. The dissolved parts resolidified during peritectic cooling and its reso lidification mode affected the growth mode of Y123 grains significantly. Th e relationship between the growth mode of Y123 grains of TSMG-processed YBC O superconductors and the resolidification nature of Sm123 seeds is reporte d. (C) 1999 Elsevier Science B.V.
