· JVASP-49201· NaTa3O8

NaTa3O8 is a mixed-metal oxide ceramic compound composed of sodium and tantalum oxides, belonging to the family of complex transition-metal oxides. This material is primarily investigated in research contexts for applications requiring high chemical stability and refractory properties, particularly in systems where tantalum's exceptional corrosion resistance and high melting point are leveraged in oxide form. Its sodium-containing composition makes it of interest in solid-state chemistry and materials science for studying ion-transport phenomena and potential electrochemical applications, though it remains largely in the development phase rather than mainstream industrial production.
