Ferroelectric Properties of Bismuth Titanate Ceramics by Pm3+/V5+ Substitution
Keyword(s):
The ferroelectricity of Bi3.25Pm0.75Ti3O12 (BPT), and Bi3.25Pm0.75Ti2.97V0.03O12 (BPTV) ceramics prepared at 1200°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 BPT ceramic are 16 μC/cm2 and 62kV/cm, respectively. Furthermore, V substitution improves the Pr value of the BPT ceramic up to 25 μC/cm2 which is larger than that of the BPT ceramic. Therefore, co-sustitution of Pm and V in Bi4Ti3O12 (BIT) ceramic is effective for the improvement of its ferroelectricity.
