Boroaluminosilicate glasses have attracted significant attention recently for applications both
as display glasses and as matrices for nuclear waste vitrification. Boroaluminosilicate
glasses have a complicated structural speciation involving two glass formers and one
intermediate species that can act as a former. The balance between network modifiers
and network formers is very important in these glasses as charge compensation effects
the roles of both alumina and boron in the glass structure and thus composition is
expected to have significant effects on the mechanical properties of these glasses.
Series of glasses with varying amounts of the glass formers and the intermediate are
being produced. The variations of their thermomechanical properties as a function of
composition are being assessed by indentation techniques, Fourier transform infra-red
and Raman spectroscopies and thermal analysis.
