--- _id: '9759' abstract: - lang: eng 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. 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.
