Abstract
In this study, we examined the chemical diffusion coefficient of oxygen out-diffusion(\(\tilde D_{out} \)) in partially melted YBa2Cu3Oy (Y123)−Ag superconducting tape produced by the thermomechanical processing of the silverclad precursor (doped with 5 wt.% Ag) containing BaCuO2.5 at reduced oxygen partial pressure (P02). The\(\tilde D_{out} \) value of Y123−Ag (O7.0 to O6.2), obtained by using the thermogravimetric relaxation technique at 950°C and a P02 of 0.28 kPa, was 1.0476×10−7 cm2/s.
