Abstract
Barium zirconium titanate ferroelectric ceramics modified with vanadium Ba(Ti 0.90Zr 0.10V 0.02)O 3 ( BZT:2V) were prepared from powders synthesized using the mixed oxide method. The effect of temperature on the structural and electrical properties of BZT:2V ceramics was investigated. X-ray diffraction data evidenced no secondary phases. As temperature decreases, the maximum dielectric permittivity decreased. The fine-grained sample showed a ‘relaxor-like’ ferroelectric behavior. The dielectric permittivity reaches a maximum value ( ɛ m ∼ 16,000 at 1 kHz) for the BZT:2V ceramics sintered at 1623 K for 4 h. Remnant polarization ( P r) and coercive field were also temperature dependent.
