· JVASP-3069· Li2CeP2

Li2CeP2 is a ternary ceramic compound combining lithium, cerium, and phosphorus elements, belonging to the family of rare-earth phosphide ceramics. This material is primarily investigated in research contexts for potential applications in solid-state ionic conductors and advanced ceramic systems, where the combination of lightweight lithium and rare-earth cerium offers potential for ion transport and thermal stability. Engineers consider rare-earth phosphide ceramics like Li2CeP2 when exploring next-generation electrolyte materials or high-temperature ceramic matrices where conventional oxides reach performance limits.
