· JVASP-17289· LiYGe

LiYGe is an inorganic ceramic compound combining lithium, yttrium, and germanium elements. This material belongs to the family of rare-earth germanate ceramics, primarily of research and development interest rather than established industrial production. The compound is investigated for potential applications in advanced optical, electrolyte, and high-temperature ceramic systems where the combination of lithium's ionic conductivity, yttrium's thermal stability, and germanium's glass-forming or structural properties may offer benefits in niche engineering contexts.
