PB-FREE PIEZOELECTRIC (NA0.53+XK0.47)(NB0.55TA0.45)O3 CERAMICS AND THEIR FABRICATION METHOD THEREOF

摘要

The present invention relates to a Pb-free (Na0.53+xK0.47)(Nb0.55Ta0.45)O3 based ceramic composition and a fabrication method thereof. More specifically a piezoelectric (Na0.53+xK0.47)(Nb0.55Ta0.45)O3 based ceramic composition is environmentally friendly unlike conventional Pb-based PZT ceramics which causes environment contamination and is harmful to human body.
