摘要

Auger electron spectroscopy (AES) and electron spectroscopy for chemical analysis (ESCA) were used to study the surface of a multicomponent lithia/alumina/silica glass-ceramic as a function of surface treatment. The glass-ceramic specimens were processed in the same manner as is presently being used in the manufacturing of glass-ceramic headers. The processing steps involve four-step solvent cleaning, sealing at high temperature, and oxide removal. At each step in the process, glass samples were studied with AES and ESCA to determine their resultant elemental surface composition and film thickness. In addition, the effect of a final plasma cleaning operation on the glass surface was also examined. The results show that the type, concentration, and thickness of surface species are dependent on the processing technique. 1 ref., 4 figs., 6 tabs. (ERA citation 14:008259)
