High-temperature synthesis and structures of perovskite and n=1 Ruddlesden-Popper tantalum oxynitrides

Abstract:

The perovskite- and K2NiF4-structure group 5 oxynitrides SrTaO2N, BaTaO2N, Sr2TaO3N, and Ba2TaO3N, previously prepared by reacting oxide precursors with ammonia, may also be prepared by the reaction between the appropriate alkaline earth oxide and TaON at 1500°C under 1 atm of pure nitrogen gas for a few hours. The nitrogen atmosphere is essential to prevent reduction of TaV, and the method of inductive heating ensures that the nitrogen atmosphere above the sample is maintained free of oxygen...
