· Li2GeO3

Lithium germanate (Li2GeO3) is an inorganic ceramic compound composed of lithium, germanium, and oxygen—belonging to the class of lithium-based ceramic oxides. This material is primarily investigated in research contexts for applications requiring thermal stability and ionic conductivity, particularly in solid-state battery systems, thermal insulators, and advanced ceramics where lithium-containing phases offer functional properties beyond conventional structural ceramics.
