The present invention is an organic field-strain properties are related to high Lead free piezoelectric ceramic composition and production method thereof, and more particularly,
(1-xy) Bi 1/ 2 Na 1/2 TiO 3 -xSrTiO 3 + yBiFeO 3
Or (1-xz) relates to a lead-free piezoelectric ceramic composition and a method of manufacturing a composition of
Bi 1/2 Na 1/2 TiO 3 -xSrTiO 3 + zLaFeO 3.
Lead-free piezoelectric ceramic composition according to the invention, applied to the piezoelectric application devices in various fields, replacing the conventional PZT piezoelectric material, including a piezoelectric actuator areas by indicating excellent electroluminescent organic strain properties even at low electric field conditions for more than 4 kV / mm possible, and in particular to indicate the applicability in applications where miniaturization and high accuracy requirements.
