· JVASP-9677· PrNbO4

PrNbO4 is a praseodymium niobate ceramic compound belonging to the family of rare-earth niobates, which are advanced ceramics valued for their thermal and chemical stability. This material is primarily of research and specialized industrial interest, used in high-temperature applications where chemical inertness and structural integrity under extreme conditions are critical. The rare-earth niobate family finds application in nuclear fuel matrices, thermal barrier coatings for aerospace engines, and solid-state electrolytes, where PrNbO4 is investigated for its potential to withstand thermal cycling and corrosive environments while maintaining phase stability.
