Hot-press sintering K0.5Na0.5NbO3–0.5 mol%Al2O3 ceramics with enhanced ferroelectric and piezoelectric properties
Source abstract
Abstract
Lead-free ceramics K0.5Na0.5NbO3–0.5 mol%Al2O3 with simple composition were prepared via the hot-press sintering. The ceramics exhibit dense microstructure, fine grains, and pure orthorhombic structure. Via the hot-press sintering as well as adding 0.5 mol%Al2O3 into K0.5Na0.5NbO3, piezoelectric and ferroelectric properties of the obtained ceramics were obviously enhanced. The ceramics exhibit high remnant polarization Pr = 26.8 μC/cm2 and piezoelectric constant d33 = 137 pC/N. The maximum unipolar strain is 0.17%, and the converse piezoelectric coefficient d33* is 212 pm/V under electric field E = 80 kV/cm. Under E = 50 kV/cm, the Pr increases from 21.6 to 22.2 μC/cm2, and the d33* increases from 223 to 322 pm/V as the temperature increases from room temperature to 170 °C. The ex situ measurement result demonstrates that d33 still keeps a high value of 97 pC/N as the annealing temperature increases to 380 °C, implying excellent thermal stability.
