The ferroelectricity of Bi3.25Eu0.75Ti3O12 (BET), and Bi3.25Eu0.75Ti2.97V0.03O12 (BETV) ceramics prepared at 1100°C by a conventional ceramic technique was investigated. These ceramics possess random-oriented polycrystalline structure. The remanent polarization (Pr) and coercive field (Ec) of the BET ceramics are 16 µC/cm2 and 62kV/cm, respectively. Furthermore, V substitution improves the Pr value of the BET ceramics up to 25 μC/cm2 which is larger than that of the BET ceramics. Therefore, co-sustitution of Eu and V in Bi4Ti3O12 (BIT) ceramic is effective for the improvement of its ferroelectricity.
