摘要：

The effects of exposing surface of the LnBa2Cu3O7-x (Ln=Y, Yb, Gd) high temperature superconductor to O 2, CO2 and moisture have been studied by post hoc XPS and SEM. Evidence is presented for incipient hydration and carbonate formation. Some factors likely to affect the susceptibility of the material to this type of "weathering" process are suggested. © 1990.
