  text: (K,Na)NbO3 ceramics have attracted much attention as lead-free piezoelectric
    materials with high piezoelectric properties. High-quality (K,Na)NbO3 ceramics
    can be sintered using KNbO3 and NaNbO3 powders synthesized by a hydrothermal method.
    In this study, to enhance the quality factor of the ceramics, high-power ultrasonic
    irradiation was employed during the hydrothermal method, which led to a reduction
    in the particle size of the resultant powders.

  text: 'A hydrothermal method utilizes a crystallization process in the solution
    so that the pure and high-quality powders can be realized. Sintering from the
    hydrothermal KNbO3 and NaNbO3 powders, a high-dense lead-free piezoelectric (K,Na)NbO3
    ceramics could be obtained (density: 98.8\%). Concerning about the g33 constant,
    high value as large as commercial PZT ceramics was measured. Therefore, the hydrothermal
    (K,Na)NbO3 ceramics is usable for the sensors and the energy harvesting devices.
    To demonstrate the (K,Na)NbO3 ceramics, a hydrophone sensor was fabricated and
    evaluated.'

  text: The hydrothermal method enables the production of high-quality piezoelectric
    materials. In this study, we propose to irradiate the reaction solutions with
    ultrasonic power during the hydrothermal method to obtain a shorter reaction time
    and a smooth film surface. A high-pressure reaction container for the ultrasonic
    transducer was newly developed, and the ultrasonically-assisted hydrothermal method
    was examined by using this container. The effect of ultrasonic assist on the synthesis
    of lead-zirconate-titanate (PZT) thin films and (K,Na)NbO$_{3}$ powders was verified.
    Thicker PZT film, thickness around 10 ${\mu}$m, could be obtained in one process,
    and (K,Na)NbO$_{3}$ powder was synthesized in half the previous reaction time.

  text: Direct ultrasound irradiation is advantageous to increase the efficiency of
    the hydrothermal method which can be used for the production of piezoelectric
    thin films and lead free piezoelectric ceramics. To apply ultrasound directly
    to the process transducer prototypes were developed regarding the boundary conditions
    of the hydrothermal method. LiNbO$_{3}$ and PIC 181 were proven as feasible materials
    for high temperature resistant transducers ($\geq 200^\circ C$). Resistance of
    the transducers horn against the corrosive mineralizer was achieved by using Hastelloy
    C-22. The efficiency of the ultrasound assisted hydrothermal method depends on
    the generated sound field. Impedance and sound field measurements have shown that
    the sound field depends on the filling level and the position and design of the
    transducer.

  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.
