All under control: Faster ammonia flow rates and higher barium/niobium ratios in precursors suppress the reduction of Nb5+ ions during nitridation. Precursors prepared by a soft-chemistry route are nitrided faster into BaNbO2N at lower temperatures than physical mixtures of BaCO3 and Nb2O5; this enables control of the physical properties of BaNbO2N.
