Plate-like single-crystalline BaBi4Ti4 particles were synthesized by the molten salt synthesis (MSS) method. The effects of sintering temperature, holding time, and NaCl–KCl molten salt content on the phase structure and morphology of plate-like BaBi4-Ti4 particles were investigated. The results show that plate-like BaBi4Ti4 particles can be synthesized when the sintering temperature is above 800C. The size of particles increases with increasing sintering temperature and molten salt content. Largely anisotropic plate-like BaBi4Ti4 particles with diameter 10m and thickness of 0.3 m can be obtained under the optimum process parameters. The crystal structure of BaBi4Ti4 was determined as A21am by TEM, which should be attributed to the Bi and Ba diffusing into [TiO6] octahedrons.
