EDX analysis and microstructural properties of the YBa2Cu3O7-delta-Ba2HoSbO6 superconducting composites

We have fabricated and characterized YBa2Cu3O7-delta-Ba2HoSbO6 a realized h igh T-c superconductor ceramic insulator composite system in which particle s of the superconductor and ceramic insulator could coexist with well defin ed separated phases left intact by stringent processing conditions. All the composites exhibit superconductivity at 92K. EDX analysis show that elemen t% and atomic% of the composites are in a good agreement with those of thei r respective components. SEM studies show homogenous surface morphology and particle size distribution. There is no detectable interface interaction b etween component grains and Ba2HoSbO6 grains are distinguishably distribute d in the YBa2Cu3O7-delta matrix.
