The Bi 4.5 Sr 0.5 Ti 4 Fe 0.5-x V x O 15 (BSTFV) solid solutions which consist of the mixture of Bi 5 Ti 3 FeO 15 and SrBi 4 Ti 4 O 15 Aurivillius phases were synthesized and the ferroelectric properties of the solid solutions were characterized in this study. The formation of solid solutions in the composition range of 0-0.05 was recognized on the basis of the variations in the lattice parameters and the small amounts of V substitution also exerted an influence on the ferroelectric properties and grain growth of BSTFV. As a result, the well-saturated P-E hysteresis loop was obtained at x = 0.03 (P r = 16µC/cm 2 and E c = 96 kV/cm).
