使用一步熔盐合成制备的板状NaNbO3 (NN)颗粒实现了(K,Na)NbO3 (KNN)陶瓷的有效取向控制。确定了抑制 KNN 陶瓷晶粒取向的因素。为了控制取向，对用于合成板状 NN 颗粒的起始材料中 Bi2O3 的混合比例进行了优化。此外，通过改进烧结工艺，制备出了取向因子为97%、相对密度为96%的织构陶瓷。
An effective orientation control of (K,Na)NbO3 (KNN) ceramics using plate-like NaNbO3 (NN) particles prepared by single-step molten salt synthesis was accomplished. The factors inhibiting the grain orientation in KNN ceramics were identified. The mixture ratio of Bi2O3 in the starting materials used to synthesize the plate-like NN particles was optimized for the orientation control. In addition, by improving the sintering process, the textured ceramics with an orientation factor of 97% and a relative density of 96% were fabricated.
