The effect of Ag addition on the microstructural and critical current densities of melt processed GdBa 2Cu 3O y /Gd 2BaCuO 5 (Gd-123/211) composites as compared to the sample without Ag are studied. Ag is found to refine Gd-211 particles to some extent. The addition of Ag resulted in a non-uniform distribution of Gd-211 in the Gd-123 matrix. The width of the platelets and gap width was found to decrease with Ag addition. Coarse Ag particles were observed to associate with Gd-211 free regions. The role of Ag was found to be different compared to that of Gd-211 particles in modifying the microstructure of the composites. The presence of Ag reduced the normal state resistivity, and marginally increased the critical current density of the material.
