| Dense single-phase BiFeO3BFO ferroelectric ceramics, with a resistivity of 1012 cm, may be formed by sintering the 450 ¡ãC-calcined coprecipitated powder at 800¨C850 ¡ãC. The ceramics sintered at 750 ¡ãC contain a second phase of Bi2O3. The conduction loss activation energies at room temperatures of 290 and 350¨C430 ¡ãC are 0.126 and 1.26 eV, respectively. The ac conductivity thermal variation suggests 290 ¡ãC as the application limit for BFO ceramics. The loss at T350 ¡ãC is higher for low frequencies than for high frequencies. In contrast, an opposite effect is found at T350 ¡ãC. © 2007 American Institute of Physics. DOI: 10.1063/1.2798256 |
