Abstract
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 compositionthat is described as composition formula {Li(KNa)}(NbSb)Oincluding 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).
