Properties of Na1/2Bi1/2TiO3 Ceramic Prepared by Sol-Gel Method

Abstract:

Article Preview

Bismuth sodium titanate ceramic was prepared by sol-gel method. The crystallization, density and microstructure were determined. The grains of BNT ceramic prepared by sol-gel method were equiaxial, ~ 2 µm, which was smaller than that prepared by solid-state reaction method. The piezoelectric and dielectric properties were investigated. When the sintering temperature was 1140°C, maximum relative dielectric constant and piezoelectric constant can be obtained. The piezoelectric constant of BNT ceramic prepared by sol-gel method was higher than those prepared by solid-state reaction method.
