摘要：
The degradation of YBa2Cu3O7-delta ceramics obtained by solid state sintering is known to be due to carbonation processes. The presence of a carbonate layer at the solid/gas interface contributes to decrease the critical current density after several months ageing in air conditions. Fluorination treatments carried out on YBa2Cu3O7-delta ceramics immediately after the sintering process increase noticeably J(c) by a curing effect of the surface. On the other hand a real passivation against ageing process is observed.
