- Abstract
- Lead-free 0.98(Na0.5K0.5Lix)NbO3-0.02Ba(Zr0.52Ti0.48)O-3 piezoelectric ceramics were investigated. The experimental results show that Li content strongly affects the orthorhombic-tetragonal morphotropic phase boundary (MPB) which results in different piezoelectric properties. The phase transition composition shows a range from 0.05 to 0.1. The sample with a composition of x = 0.1 showed the maximum values of piezoelectric coefficient (d(33) = 201 rho C/N), electromechanical coupling coefficient (k(p) = 39%), and remnant polarization (P-r = 21 mu C/cm(2)).
