摘要：

Bismuth sodium titanate Bi0.5Na0.5TiO3 ceramic With about 96% of,theoretical density was prepared by sol-gel processing. The saturate P-E hysteresis loop can be obtained under a 100kV/cm AC electric field for the sol-gel processed Bi0.5.,Na0.5,TiO3 Ceramic and the remanent polarization P-r and coercive field E-c are 32muC/cm(2) and 61kV/cm, respectively. Moreover, from the piezoelectric. measurements, this material fabricated by sol-gel processing was found to have increased piezoelectric constant d(33)=102 x 10(-12)C/N and electromechanical coupling factor k(t), = 58%. Therefore, sol-gel method is. a potential fabrication, technique for this lead-free piezoelectric ceramic.
