Textured Tl(1223)/Ag tapes prepared by electrophoretic deposition

The conventional powder-in-tube technique does not allow to produce textured Tl(1223) tapes. An electrophoretic deposition technique was used to produce uniform layers of controlled thickness on Ag substrates by a simple and reproducible procedure. A high degree of texture, comparable with the one generally observed for Bi-based tapes was obtained thanks to the appropriate grain morphology, by simply alternating deposition and uniaxial pressing. After annealing, critical current densities of 11'000 A/cm2 were reached
