Synthesis of Nano-sized Barium Titanate Powder by Solid-state Reaction between Barium Carbonate and Titania

BaTiO3 在的尺寸控制固态在 BaCO3 和 TiO2 之间的反应被改变更高有的 BaCO3.The 更小的 TiO2 粒子的 TiO2 和 milling 条件的尺寸表明表面区域，导致更快的起始的反应。机械地， milled BaCO3 粒子加速了散开过程并且减少锻烧温度。它能从结果被推出尺寸控制可能、缩放 nano 有大约 60 nm 的 BaTiO3 粒子能被使用综合常规固态在 BaCO3 和 TiO2 之间的反应。

Size control of BaTiO3 in solid-state reaction between BaCO3 and TiO2 was demonstrated by varying the size of TiO2 and milling conditions of BaCO3. The smaller TiO2 particles had higher surface area, resulting in faster initial reaction. The mechanically milled BaCO3 particles accelerated the diffusion process and decreased the calcinations temperature. It can be deduced from the results that the size control is possible and nano-sized BaTiO3 particles with about 60 nm can be synthesized by using the conventional solid-state reaction between BaCO3 and TiO2.
