Abstract

Abstract The refinement of Y 2BaCuO 5 (Y211) particles by CeO 2 in the single-grain YBa 2Cu 3O 7/Y 2BaCuO 5 (Y123/Y211) bulk superconductors of nominal composition Y 1.5Ba 2Cu 3O x prepared by top-seeded melt-growth process with Y 2O 3 addition has been studied by polarised light microscopy. It is shown that cerium is active in the Y211 particle refinement when it is solved in the peritectic melt, L p. Observed growth of Y211 particles during sintering stage is ascribed to higher amount of melt induced by CeO 2 reaction with Y123 phase producing barium cerate and CuO.
