Molten Salt Synthesis of Anisotropic Bi4Ti3O12 Particles
Plated-like Bi4Ti3O12 particles with anisotropic properties were prepared by the NaCl-KCl molten salt method. The effect on microstructure and patterns of Bi4Ti3O12 particles was investigated by adjusting salt quantities, calcined temperature and excessive Bi2O3 content. The results show that the size of Bi4Ti3O12 particle and the degree of anisotropy of pure perovskite structure of Bi4Ti3O12 particles prepared at 750°C simultaneously increased with the quantities of molten salt and the temperature of the calciner. Excessive Bi2O3 content also shows a positive effect to obtain the anisotropic Bi4Ti3O12 particles whose preparation process was optimized.
