Synthesis of Single-Crystalline Plate-shaped K0.5Na0.5NbO3 Particles by Multi-step Molten Salt Method Zhi Liu, Yue-Ming Lia, Zong-Yang Shen, Zhu-Mei Wang School of Materials Science and Engineering, Jiangxi Key Laboratory of Advanced Ceramic Materials, Jingdezhen Ceramic Institute, Jingdezhen 333403, China a lym6329@yahoo.com.cn Keywords: Piezoelectric ceramics; Multi-step molten salt method; Perovskite Abstract.
First, precursor particles K4Nb6O17 (K4N6) with layer-structure was synthesized at 1050 °C in molten KCl-salt (MMSM-1) by starting materials of Nb2O5 and K2CO3.
Preparation of KNN from K4N6 precursors: Using K4N6, potassium carbonate (K2CO3, SCRC), potassium chloride (KCl, SCRC) and sodium chloride (NaCl, SCRC) as raw materials, KNN was converted from K4N6 by MSM according to the following Eq. 2.
Meanwhile, both KCl and NaCl were used as raw materials and molten salts in this reaction, and the total weight of KCl and NaCl was equal to K4N6 and K2CO3 [13].

Editorial Scanning tunneling microscopy (STM) is a non-optical microscope, useful for surface science studies.
It has been used extensively to study the defects and physical structure of synthetic nano materials and interfaces at nano level.
We are in the 8th volume now and slowly rising to a prospective journal.

The relationships of physical parameters and temperature should be defined accurately to giving initial conditions, such as the thermal expansion of the materials of the seal rings.
The rotating ring and the stationary ring are composed by different materials, the different thermal resistance leads to thermal distribution inequality.
