--- _id: '9758' abstract: - lang: eng 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. author: - first_name: Takafumi full_name: Maeda, Takafumi last_name: Maeda - first_name: Norihito full_name: Takiguchi, Norihito last_name: Takiguchi - first_name: Takeshi full_name: Morita, Takeshi last_name: Morita - first_name: Mutsuo full_name: Ishikawa, Mutsuo last_name: Ishikawa - first_name: Tobias full_name: Hemsel, Tobias id: '210' last_name: Hemsel citation: ama: Maeda T, Takiguchi N, Morita T, Ishikawa M, Hemsel T.
