Abstract Tl-based high-T c oxide layers have been synthesized through the reaction between Tl-free substrate and coating layer containing Tl. The coating layer with the eutectic composition in V2O5-Tl2O3 system much enhances the formation of Tl-2223 phase without degrading its superconducting properties. The TIF substitution for T12O3 in the coating layer promotes the formation of Tl-1223 phase, which significantly improves the I c-B performance at higher temperatures. The behavior of F during the reaction has been studied. Thick Tl-1223 layer is formed on Ni tape with good bonding through the diffusion reaction.
