The ferroelectricity of Bi3.25Tm0.75Ti2.97V0.03O12 (BTTV) ceramic prepared at 1200°C by a conventional ceramic technique was investigated. The ceramic possess random-oriented polycrystalline structure. The remanent polarization (Pr) and coercive field (Ec) of the BTTV ceramics are 25 μC/cm2 and 70kV/cm, respectively. The Pr value of the BTTV ceramics up to 25 μC/cm2 is larger than that of the BTT ceramics. Therefore, co-sustitution of Tm and V in Bi4Ti3O12 (BIT) ceramics is effective for the improvement of the ferroelectricity of Bi4Ti3O12 ceramics. |
