Abstract
- Barium titanate gels were prepared from barium acetate and tetrabutyl titanate by sol-gel processing. The results of DTA and XRD showed that as-prepared gels were transformed into crystalline with tetragonal ferroelectric phase by a heat treatment at 600°C. It was found that soaking the BaTiO3 crystalline powders in nitric acid could increase the density of the ceramic bodies. The density of the resultant bodies is near 96% of the theoretical value. The dielectric measurement on most of the ceramic bodies showed that the magnitude of dielectric constant is 16,000 at its peak and 2500 at room temperature. D-E hysteresis loop was observed.
