Enhancement of Q/sub m/by Co-Doping of Li and Cu to Potassium Sodium Niobate Lead-Free Ceramics

摘要

Lead-free piezoelectric ceramics KNN modified by Li-substitution and CuO addition have been synthesized, and the piezoelectric and dielectric properties were measured. A morphotropic phase boundary (MPB) between orthorhombic and tetragonal phases was form
