Zusammenfassung

Entsteht aus dem Dihydrat (s. unten) durch Entwässerung bei 140°C und zersetzt sich unter CO2-Abspaltung bei 230 bis 260°C, wobei ein Rückstand der Zusammensetzung Na3NbO3C2O · 2 CO erhalten wird, der unter CO-Abspaltung bei etwa 500°C in Na3NbO4 übergeht. An feuchter Luft bildet sich aus Na3NbO(C2O4)3 das Dihydrat, L. G. Vlasov, A. V. Lapitskii, M. A. Salimov, B. V. Strizhkov (Zh. Neorgan. Khim. 7 [1962] 2534/6; Russ. J. Inorg.
