· JVASP-4325· LuSi2

Lutetium disilicide (LuSi₂) is a ceramic intermetallic compound belonging to the rare-earth silicide family, characterized by a hexagonal crystal structure typical of higher-order silicides. This material is primarily of research interest for high-temperature structural applications where its thermal stability and potential oxidation resistance at elevated temperatures make it a candidate for advanced aerospace and power-generation components, though it remains largely in development stages compared to more established refractory ceramics like MoSi₂.
