Implication

Experimental analysis demonstrates localized compositional shifts in alkali silicate glasses during electron microprobe testing, highlighting beam-induced mobile ion migration.

Key Points

Investigate localized compositional changes and alkali element instability in alkali silicate glasses during electron microprobe microanalysis.
Subjected alkali silicate glass specimens to focused electron beam irradiation during microprobe analysis.
Tracked localized compositional shifts and signal decay across the irradiated specimen areas over analysis intervals.
Electron beam exposure induces measurable local compositional modifications within the interaction volume of alkali silicate glasses.
Mobile alkali cations migrate away from the electron beam excitation zone, altering characteristic elemental intensities.
