Abstract

© 2013 Elsevier B.V. All rights reserved. A bulk YBa 2 Cu 3 O 7- δ (YBCO)/Ag superconducting composite with a homogenous distribution of fine and spherical particles of metallic Ag and Y 2 BaCuO 5 (Y-211) has been fabricated by employing Directionally Solidified Preform Optimized Infiltration Growth Process (DS-POIGP). The effect of adding Ag into the liquid phase source (YBa 2 Cu 3 O 7- δ ) placed above the Y-211 preform on the microstructures and current densities is investigated. The addition of Ag led to a significant refinement of Y-211 particle size and, hence, enabled the enhancement of current densities at low fields.
