Abstract:

The O_(1s) binding energies of MgO, ZrO_2, TiO_2, Al_2O_3 and SiO_2 were determined by XPS. It is shown that the BSCCO-oxides interactions are predominately acid-base in nature, and the reactivity can be evaluated either by the acid-base parameter or by the core-level binding energy of oxygen of the oxide substrate materials.

Key words: Bi-Sr-Ca-Cu-O superconductor, Solid acid-base reaction, XPS
