C. Leblond-harnois et al., Texturing process, superconducting and mechanical properties of Ag-doped top-seeded melt-grown YBCO pellets, PHYSICA C, 341, 2000, pp. 2439-2440
Pellets of YBa2Cu3O7-delta doped with a mixture of ceria (0.5 wt %) and sil
ver (5 and 10 wt %) were textured using the top-seeding melt-texturing proc
ess with a maximum temperature of 1000 degreesC. 430 degreesC was found to
be an optimum annealing temperature for textured silver doped YBCO and Bean
critical current densities of 55 kA/cm(2) were measured under self field.
Both the fracture toughness and the resistance to thermal shock have been i
mproved by the addition of silver.
