text: Among various lead-free piezoelectric materials, (K,Na)NbO$_{3}$ is a very
promising candidate. In this study, (K,Na)NbO$_{3}$ ceramics were sintered from
mixed (K,Na)NbO$_{3}$ and NaNbO$_{3}$ powders prepared by hydrothermal reaction.
These two powders were mixed with distilled water in a KNbO$_{3}$/NaNbO$_{3}$
molar ratio of 1. After sintering the mixed powder, the solid solution of (Na,K)NbO$_{3}$
ceramics was obtained. The electrical properties such as the electromechanical
coupling factors k$_{p}$ and k$_{33}$, the mechanical quality factor, Q$_{m}$,
and the piezoelectric constant d$_{33}$ of the sintered (K,Na)NbO$_{3}$ ceramics
were 0.32, 0.48, 71 (radial mode), 118 ((33)mode), and 107 pC/N, respectively.
