THE ROLE OF SURFACE BORON AS ADSORPTION CENTER FOR THE SORPTION OF WATER BY POROUS GLASS.

Abstract

The changes in the infrared spectra of porous glass surfaces produced by sorption of water at room temperature were recorded. Highly dehydroxylated, deuterated, and fluoridated surfaces were examined. Prominent spectral changes are associated with a band at 3703/cm ascribed to surface B-OH structures. There is evidence to show that surface boron is the adsorption center for the hydration of highly degassed porous glass. Direct comparison of highly-degassed porous glass surfaces with pure silica surfaces is consequently not valid. (Author)
