Below 4.2 K is the onset of superconductivity in sodium niobates Na x NbO 2 for values of x between 0.65 and 0.9. The samples studied all contain two phases, a sodium‐rich phase, which is isostructural with NaNbO 2 , and a sodium‐poor phase with a related layered structure. The latter phase exhibits superconductivity.
