text: As a lead-free piezoelectric ceramics, (K,Na)NbO$_{3}$ is a promising material
because of its good piezoelectric properties. In this study, (K$_{1-x}$Na$_{x}$)NbO$_{3}$
ceramics were synthesized from a KNbO$_{3}$ and NaNbO$_{3}$ mixture powder prepared
by the hydrothermal reaction. The hydrothermal reaction enables the production
of high quality powder for the ceramics fabrication process. To obtain (K$_{1-x}$Na$_{x}$)NbO$_{3}$
ceramics, these two powders KNbO$_{3}$ and NaNbO$_{3}$ were mixed and then sintered
together. X-Ray diffraction analysis revealed that the solid solution ceramics
(K$_{1-x}$Na$_{x}$)NbO$_{3}$ was produced by the sintering process. The K/Na ratio
in (K$_{1-x}$Na$_{x}$)NbO$_{3}$ ceramics was optimized for the best piezoelectric
properties. The optimized forms was (K$_{0.48}$Na$_{0.52}$)NbO$_{3}$, which showed
the following piezoelectric properties; k$_{33}$=0.56, d$_{33}$=114pC/N. In addition,
the ferroelectric properties, P$_{r}$=7.72mC/cm$^{2}$, E$_{c}$=857V/mm, and the
Curie temperature T$_{c}$=420$_{o}$C were also measured.
