· JVASP-44217· CeW2O8

CeW2O8 is a cerium tungstate ceramic compound that belongs to the rare-earth oxide family, combining cerium and tungsten in an 1:2 molar ratio. This material is primarily investigated in research contexts for high-temperature applications and as a potential thermal barrier or functional ceramic, leveraging cerium's oxidation resistance and tungsten's refractory properties. The compound has potential relevance to aerospace thermal protection systems and specialized industrial heating environments, though it remains largely in the developmental/experimental phase compared to established thermal barrier coatings.
