Infiltration growth processing of single grain (Gd,Dy)BCO bulk superconductors: optimization of liquid phase mass and characterization of physical properties

Popis výsledku v původním jazyce

Infiltration of an optimal amount of liquid (Ba3Cu5O8 denoted further as “035”) for efficient peritectic growth is a primary requirement in the infiltration growth (IG) processing of high-quality REBa2Cu3O7-δ products. Recently, we optimized the Dy content and the time-temperature schedules for top-seeded IG processing of (Gd,Dy)Ba2Cu3O7–δ [(Gd,Dy)BCO] single grain superconductors. Aiming to fabricate larger sized (Gd,Dy)BCO (80wt.% Gd2BaCuO5 and 20wt.% of Dy2BaCuO5) single grain bulk superconductors, different liquid phase [LP=ErBa2Cu3O7–δ (Er-123) and mixed with 035] sources were employed and the LP content was optimized by varying its mass. The increase in Er-123+035 mass assured an abundant amount of liquids for peritectic reaction. The Er-123+035 ratio of 1:1.4 was found to be optimum. The optimized liquid phase infiltration enabled an effective control of (Gd,Dy)2BaCuO5 (211) secondary phase size and content in final microstructures.
