· JVASP-8826· Na2CeO3

Sodium cerium oxide (Na2CeO3) is an inorganic ceramic compound combining alkali and rare-earth elements, belonging to the family of mixed-metal oxides. This material is primarily of research interest in advanced ceramics and materials science, with potential applications in solid-state ionics, catalysis, and thermal barrier coatings where the chemical stability of cerium oxides and the ionic conductivity benefits of sodium-containing phases can be leveraged. Engineers considering this compound should recognize it as an emerging material rather than an established commercial product, relevant when exploring novel ceramic systems for high-temperature environments or electrochemical applications.
