- Abstract
BaZr0.1Ti0.89Fe0.01O3 ceramics sintered at 1240–1340 °C were prepared by solid-state method. The sample underwent phase transition from rhombohedral to orthorhombic phase, which changed the internal stress. Increasing the sintering temperature promoted grain growth (from 0.44 to 1.87 μm). The dielectric constant (ε = 4300) and diffusion coefficient (γ = 1.927) of the sample were improved significantly. The improvement mechanism of dielectric constant and dispersion phase transition was explained by the internal stress model and 90° domain structure in detail.
