    Description / Table of Contents: Die thermische Zersetzung von Nb3O7Cl und NbO2FDie thermische Zersetzung von Nb3O7Cl in Argon sowie Sauerstoff wurden untersucht und folgende Reaktionen gefunden: Die Zersetzungsprodukte in beiden Atmosphären waren T-Form- und H-Form-Nb2O5. Es wurde jedoch beobachtet, daß die Impfung des Ausgangsmaterials Nb3O7Cl mit der besonderen polymorphen Nb2O5-Form zu einem groß Anteil dieser Form im Zersetzungsprodukt führt.NbO2F wurde in Sauerstoffatmosphäre zersetzt. Das Zersetzungsprodukt war P-Form-Nb2O5, das in N-Form-Nb2O5 überging. Bei der thermischen Zersetzung von NbO2F wurde kein Impfeffekt beobachtet.
    Notes: The thermal decompositions of Nb3O7Cl in atmosphere of argon and oxygen were carried out and the decomposition formulae were determined as follows: The decomposition products in each atmospheres were found to be the T-form Nb2O5 and H-form Nb2O5. It was, however, observed that if an amount of special polymorphic form of Nb2O5 has been added to the starting material, Nb3O7Cl, the decomposition product came to contain a larger proportion of the seeded form.NbO2F was decomposed in the oxygen atmosphere. The decomposition product appeared as the P-form Nb2O5 and transformed into the N-form Nb2O5. In the case of the thermal decomposition of NbO2F, no appreciable seeding effect was observed.
