Abstract:	Dielectric properties of SrBi2(V0.1Nb0.9)2O9 (SBVN) were investigated in a broad range of temperatures (400-1000 K) and frequencies (1 Hz to 10 MHz). Strong dielectric relaxation at the ferroelectric transition temperature was observed. The effect of post-sinter annealing on the frequency dispersion of SBVN and the possible mechanisms for the observed dielectric relaxation are presented. Electron paramagnetic resonance and x-ray photoelectron spectroscopy investigations provide direct evidence for the existence of lower valence state of vanadium (V4+) in SBVN ceramics.
