· JVASP-9973· LiTaGeO5

LiTaGeO₅ is a lithium tantalate germanate ceramic compound belonging to the family of mixed-metal oxide ceramics. This material is primarily of research interest for its potential in optoelectronic and photonic applications, where its crystal structure and ion-conducting properties make it a candidate for integrated photonic devices and solid-state electrolyte development. While not yet widely deployed in mainstream commercial products, materials in this compositional family are being investigated for next-generation optical modulators, frequency converters, and all-solid-state battery electrolytes where chemical stability and ion transport characteristics are critical.
