· JVASP-11168· SmNbO4

SmNbO4 is a rare-earth niobate ceramic compound combining samarium and niobium oxide in a stable crystal structure. This material is primarily investigated in research contexts for applications requiring high-temperature stability and dense ceramic phases, particularly in environments where thermal cycling or chemical corrosion resistance is critical. SmNbO4 belongs to the broader family of rare-earth niobates, which are of interest as potential thermal barrier coatings, nuclear fuel hosts, and specialized refractory ceramics where conventional oxides show limitations.
