采用水热法,以硫酸镍和硫酸镁为主要原料,在150 ℃制备出结构稳定的NiO-MgO纳米粒子. 并用扫描电子显微镜、X射线衍射和能谱等测试技术对NiO-MgO纳米粒子的结构和形貌进行表征. 表征结果显示,制得的NiO-MgO呈颗粒状,其直径为10～40 nm. 水热法制得的粉体和经过380 ℃煅烧所得的样品,结构和形貌基本保持不变;经690 ℃高温煅烧后,形成了良好的NiO-MgO固溶体,晶化程度提高,分散性比较.

NiO-MgO nano-particles were successfully prepared by the hydrothermal method with NiSO4 and MgSO4 as raw material. Microstructure and morphology of the product were characterized by means of scan electron microscopy, X-ray diffraction and energy dispersive X-ray spectroscopy. The results show the particle has a sphere-like apparent structure, and the diameter of the particle is in a range of 10 - 40 nm. Compared with the particles prepared by the hydrothermal method, the microstructure and morphology of the sample sintered at 380 ℃ remain unch...
