(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.
(K,Na)NbO3 陶瓷作为具有优异压电性能的无铅压电材料受到了广泛关注。使用水热法合成的 KNbO3 和 NaNbO3 粉末可以烧结出高质量的 (K,Na)NbO3 陶瓷。在这项研究中，为了提高陶瓷的品质因数，在水热法中采用了高功率超声波辐照，从而导致所得粉末的粒径减小。
