The diffusion reaction between a high melting point substrate and a low melting point coating layer may produce denser and more uniform high-Tc oxide phases than those prepared by a conventional powder sintering process. Meanwhile, the T1-Ba-CaCu-0 (TBCC0) system is an attractive one due to its highest transition temperature Tc among superconducting oxides.1 In this paper, superconducting properties and structures of the TBCCO high-Tc phase formed by the diffusion reaction will be reported.
