EDX analysis and microstructural properties of the YBa₂Cu₃O_7-δ-Ba₂HoSbO ₆ superconducting composites

We have fabricated and characterized YBa₂Cu₃O_7-δ-Ba₂HoSbO ₆ a realized high T_c superconductor -ceramic insulator composite system in which particles of the superconductor and ceramic insulator could coexist with well defined separated phases left intact by stringent processing conditions. All the composites exhibit superconductivity at 92K. EDX analysis show that element% and atomic% of the composites are in a good agreement with those of their respective components. SEM studies show homogenous surface morphology and particle size distribution. There is no detectable interface interaction between component grains and Ba₂HoSbO₆ grains are distinguishably distributed in the YBa₂Cu₃O_7-δ matrix.
