Ferroelectric Properties of Bismuth Titanate Ceramics by Eu³⁺/V⁵⁺ Substitution

Abstract:

The ferroelectricity of Bi_3.25Eu_0.75Ti₃O₁₂ (BET), and Bi_3.25Eu_0.75Ti_2.97V_0.03O₁₂ (BETV) ceramics prepared at 1100°C by a conventional ceramic technique was investigated. These ceramics possess random-oriented polycrystalline structure. The remanent polarization (P_r) and coercive field (E_c) of the BET ceramics are 16 µC/cm² and 62kV/cm, respectively. Furthermore, V substitution improves the P_r 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.
