Characterization of （NaBi）_0.5TiO₃ Ceramic Fabricated by Solid Reaction and Citrate Method

Solid reaction and citrate method were employed to prepare（NaBi）_0.5TiO₃ ceramic powder.The granularity,phases,microstructure and other characters of the ceramic powder and ceramic were investigated by using laser granularity analyse appa-ratus,XRD,SEM and the piezoelectric constant d₃₃ of the ceramics was also detected under different sintering temperatures.The results showed that NBT ceramic prepared by citrate method has lower sintering temperature and the more favorable piezo-electric property than that prepared by solid reaction.When the sintering temperature is 1150℃,the piezoelectric constant d₃₃ can reach 61.6pc/n.
