· JVASP-50362· BaNa4O3

BaNa₄O₃ is an inorganic ceramic compound combining barium, sodium, and oxygen—a mixed-metal oxide belonging to the family of alkaline-earth and alkali metal oxides. This material is primarily of research interest rather than established industrial use; it represents compositions being investigated for potential applications in solid electrolytes, thermal barrier coatings, or specialized refractory environments where the combined ionic properties of barium and sodium offer unique phase stability or conductivity characteristics.
