Bi2O3 NaKLiNbO3 NaKLiNbO3 SYSTEM Pb-FREE PIEZOELECTRIC CERAMICS WITH Bi2O3 ADDITION

摘要

The present invention relates to a (Na,K,Li)NbO 3 based lead-free piezoelectric ceramic to which Bi 2 O 3 is added. It is intended to make it happen. That is, in the lead-free piezoelectric ceramic, Bi 2 O 3 is added and a lead-free piezoelectric ceramic body composed of (Na,K,Li)NbO 3 system and a skin current connection electrode provided on both sides of the lead-free piezoelectric ceramic body. It is characterized in that it is composed. Accordingly, the present invention has the effect of minimizing environmental pollution by manufacturing the lead-free piezoelectric ceramic body without lead, and the effect that the electric signal supply is clearly made without loss through the skin current connection electrode and the wire source is clearly bound.
