· NaNbO2

Sodium niobate (NaNbO2) is an inorganic ceramic compound belonging to the metal oxide family, characterized by a perovskite-related crystal structure. It is primarily of research and development interest for applications requiring high-temperature stability, ionic conductivity, and chemical durability, with potential use in solid-state electrolytes, photocatalysis, and specialized refractory applications. Engineers consider this material when conventional oxides prove inadequate for demanding thermal or electrochemical environments, though it remains less established in high-volume production compared to yttria-stabilized zirconia or alumina ceramics.
