以Ti(OC_4H_9)_4 、Ba(NO_3)_2 和C_4H_6MnO_4·4H_2O为原料,采用微波水热法合成了Mn掺杂的BaTiO_3纳米粉体.通过X射线衍射(XRD)和扫描电子显微镜(SEM)对产物进行了表征.并研究了影响Mn掺杂BaTiO_3晶体生长和形貌的主要影响因素.实验结果表明:掺杂量为1.0%,反应时间为30 min,烘箱干燥温度为82 ℃,能制备出单一的粒径均匀的掺Mn的BaTiO_3纳米粉体,且粉体的粒径尺寸约为100 nm.
The Mn-doped barium titanate nano-powders were synthesized by Microwave-hydrothermal Method, in which Ti(OC_4H_9)_4 、Ba(NO_3)_2 and C_4H_6MnO_4·4H_2O compounds were used as raw materials. The Mn-doped Barium Titanate nano-powders were characterized by means of X-ray diffraction (XRD) and scanning electron microscope (SEM). The primary effects of processing parameters on the growth and morphology of the Mn-doped Barium Titanate were studied. The experimental results showed that the Mn-doped Barium Titanate of pure phase and uniform size was obtained when the concentration of Mn, the reaction time and drying temperature were 1.0%, 30 min and 82 ℃, respectively. And the size of the Mn-doped Barium Titanate powders was about 100 nm.
