Development of lead-free (Bi 1/2 Na 1/2)BaTiO3 piezoelectric ceramics for clinical applications.
The present paper provides a method for the manufacture of lead-free piezoelectric ceramics, based on Bismuth-Sodium Titanate (Bi 1/2 Na 1/2)BaTiO3 commonly abbreviated as BNBT. Also, this paper shows the characterization of this piezoceramics, like the Curie temperature, the dielectric constant, resonant frequency, etc. This piezoceramics can be used in medical application where a high frequency transducer is needed as well as ultrasound.
