Studies on the structure of boron-containing glasses have been well documented by Griscom (1). The techniques described in those studies are, in general, electromagnetic “probes”, e.g. X-ray diffraction, electron spin resonance, etc… An alternate method was suggested in 1962 by Doremus (2), viz. a careful analysis of the solution of relatively small diameter gas atoms or molecules in the glass network structure. More recently, the authors (3) have described a particular version of this method referred to as the “gas probe technique”. It is based on a statistical thermo-dynamic analysis of the gas solution process. A description follows in the next section. In general, the analysis provides values for the binding energy between a dissolved helium atom and the glass network and the vibrational frequency of the atom. This information, in turn, describes the potential energy well for the dissolved atom. The potential well is a direct result of the glass network structure in the immediate vicinity of the dissolved atom, i.e. the solubility site.
