· JVASP-50424· CeHfO4

CeHfO4 is a ceramic compound combining cerium and hafnium oxides, belonging to the family of rare-earth hafnate materials. This is primarily a research-stage material investigated for high-temperature structural and functional applications where thermal stability and chemical inertness are critical. The cerium-hafnium oxide system shows promise in aerospace thermal barriers, nuclear fuel surrogates, and advanced refractory applications where conventional oxides reach performance limits, though it remains largely in development rather than mainstream industrial production.
