We studied the mechanism of (RE)Ba₂Cu₃O_y phase formation via (RE)₂BaO₄ in the case of GdBa₂Cu₃O_y + 40 mol% Gd-211 combination, using mixture of Gd₂BaO₄, BaCuO₂ and CuO. Pellets of this composite were sintered at various temperatures between 700 °C and 1100 °C and held for 1 h in Ar (100%), Ar-1% O₂, Ar-0.1% O₂ atmospheres, then rapidly quenched in oil. The samples were characterized by XRD, SEM, and EPMA analyses. XRD and EPMA analyses indicated that Gd-123 phase forms at around 900 °C but the temperature depends on the chosen atmosphere. The samples quenched from high temperatures (>1000 °C) showed that final formation of a secondary phase depends on the temperature held before the quench.
