Paper Title:
Na1-xKxNbO3 (x=0.2~0.8) Lead-Free Piezoelectric Ceramics Prepared by Spark Plasma Sintering
  Abstract

Highly dense Na1-xKxNbO3 (x=0.2~0.8) ceramics were successfully prepared using spark plasma sintering (SPS) at temperature as low as 920°C. Solid solutions were formed during the composition range investigated. The piezoelectric constant and planar mode electromechanical coupling coefficient are significantly dependent on the Na/K ratio, with the maximum value of 148 pC/N and 38.9% at the composition Na0.5K0.5NbO3.
