Calorimetric, Raman and electrical conductivity properties of alkali borates ${(100-x)}\text{B}_2\text{O}_3\text{-}x\text{M}_2\text{O}$ ($\text{M}=\text{Li}$ , Na) are studied as a function of composition $(x)$ and these show the presence of stiffness transitions and an intermediate phase which are driven by a combination of network dimensionality change and usual topological constraint changes. This picture is confirmed by a detailed Raman analysis showing that specific modes of molecular structural groupings dominate the network structure in the intermediate phase. Their evolution shows a one-to-one correspondance with the observed non-reversing heat flow at the glass transition, and are correlated with thresholds in ionic conductivity ...
