Piezoelectric ceramic composition
This invention provides for a piezoelectric ceramic composition having a lead-free alkaline niobate piezoelectric ceramic composition with a favorable piezoelectric property. This invention refers to a piezoelectric ceramic composition 10 that is described as composition formula {Lix(K1-yNay)1-x}(Nb1-zSbz)O3 including the additives of the metallic elements Bi and Fe within the range of the following relational expressions: 0.03≰x≰0.045; 0.5≰y≰0.58; 0.03≰z≰0.045; and 0.006≰v≰w≰0.010 whereof v is the additive amount of Bi (molar ratio), and w is the additive amount of Fe (molar ratio).
