【摘要】 以FeCl₃ 为原材料利用溶胶凝胶法制备α-Fe₂O₃ 纳米粉,应用X 射线衍射和扫描电镜研究干凝胶晶化温度对α-Fe₂O₃ 的晶态转变以及粒子形貌和尺度的影响。实验表明,在300℃处理2h获得10～12nm均匀纳米粒子。更多还原

【Abstract】 α-Fe₂O₃ nanopowder was prepared by Sol-Gel method using FeCl₃ as raw material. Effect of temperature oncrystal transition, morphology and size on α-Fe₂O₃ powder have been investigated using x-ray diffraction and scanningclectron microscopy Experimental results show that 10-12nm of α-Fe₂O₃ powder was abtained at temperature 300℃for two hours.更多还原
