Abstract :
The present paper provide a method to obtain lead-free piezoelectric ceramics based on bismuth sodium titanate (Bi1/2Na1/2)BaTiO3 (BNBT), as well as the characterization of these, the elaboration consists from the dust mixture to the sinterized the pieces in a furnace, the BNBT systems had been studied for its dielectrics and piezoelectric properties, the characterization consists of determining the Curie temperature and resonance frequency. BNBT ceramics present similar characteristics to those of the PZT ceramics. Because of its high frequency of resonance they can be used in biomedical applications, concretely in ultrasound applications.
