Abstract

In this study, we examined the chemical diffusion coefficient of oxygen out-diffusion (D̃out) in partially melted YBa₂Cu ₃O_y (Y123)-Ag superconducting tape produced by the thermomechanical processing of the silverclad precursor (doped with 5 wt.% Ag) containing BaCuO_2.5 at reduced oxygen partial pressure (P _O2). The D̃_out value of Y123-Ag (O_7.0 to O_6.2), obtained by using the thermogravimetric relaxation technique at 950°C and a P_O2 of 0.28 kPa, was 1.0476 × 10 ^-7 cm²/s.
