摘要：

The dielectric films consisted of the barium titanate (BaTiO3) powder particle and the polymer were fabricated using the sodium chloride (NaCl)-flux treatment to investigate the effect of the molten salt on the dielectric properties of the BaTiO3 particles. The BaTiO3 particles for the NaCl-flux treatment were prepared by calcining the mixture of the BaTiO3 and the NaCl at the various temperatures. The NaCl-flux treated BaTiO3 particles showed the smooth surface and high crystallinity compared to the non-treated BaTiO3 particles, because the BaTiO3 particles were recrystallized by NaCl-flux treatment. In addition, high dielectric performances of a 20 % increase in the dielectric constant, a 40 % decrease in the dielectric loss, and a 280% increase in the dielectric strength were achieved. The dielectric films of the NaCl-flux treated BaTiO3 particles could induce the high dielectric performances due to the improvement of the crystallinity with highly packing density.
