dc.description.abstractUltra-fine NaNbO3 powder was prepared by the use of polymeric precursors. X-ray diffraction (XRD) results showed that this niobate nucleates from the amorphous precursor, with no intermediate phases, at low temperature (500°C). Studies by XRD and nitrogen adsorption/desorption showed that powders with high crystallinity ( ≈ 100%) and high surface areas (>20 m2/g) are obtained after calcination at 700°C for 5 h. Compacts of calcined powders showed high sinterability reaching 98% of theoretical density when sintered at 1190°C for 3 h.en
