Abstract

NKLN-BZT ceramic microstructure and electric properties were studied with a special emphasis on the influence of sintering temperature in the range of $1070^{\circ}C-1110^{\circ}C$. The result of XRD analysis indicates that the orthorhombic phase was found at the temperature of $1090^{\circ}C$, and those samples show the maximum values of piezoelectric coefficient ($d_{33}\;=\;200\;_{\rho}C/N$), electromechanical coupling coefficient ($k_{\rho}$ = 38%), and remnant polarization ($P_{r}\;=\;24\;{\mu}C/cm^{2}$).
