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.
