Structural investigations on two typical lithium germanate melts by<i>in situ</i>Raman spectroscopy and density functional theory calculations

Abstract

<italic>In situ</italic>Raman spectroscopy, together with density functional theory calculations, was used to monitor the structural changes of polycrystalline Li₄GeO₄and Li₆Ge₂O₇from room temperature to their melting temperatures.
