Chemical relaxations at the glass transition of a lithium-conducting glass

A systematic Raman and ir study of Li metaborate glass devitrification was done to reveal the chemical transformations of the borate network upon melt quenching. Spectra indicated that the glass showed structural similarities to the three distinct polymorphs resulting from its devitrification. Results seemed to link glass-forming ability with a nonhomogeneous glass structure. 27 refs.
