✦ Synopsis

A high-pressure Raman scattering study reveals that crystalline Li2GeO 3 and Li6Ge207 transform into the amorphous state at 12 and 11 GPa respectively. The pressure-induced amorphizations are reversible within a certain range above the starting transition pressure and are irreversible above 20 GPa. The pressure-induced amorphization of the series of lithium germanate crystals is closely related to their composition and structure: with increasing Li20 content of these crystals the amorphization transition pressure decreases.
