摘要: 采用溶胶-凝胶表面包覆法制备了纳米Fe2O3-Al2 O3复合材料, 利用X射线衍射和透射电镜对样品的物相、 粒度和形貌进行了研 究. 结果表明, α-Fe2O3掺杂降低了Al2O3相变温度, 在900 ℃可以得到稳定的α-Al2O3相.

Abstract: Fe2O3-Al2O3 nano-composit e was prepared by sol-gel and the phase, particle size and surface characterizat ion of samples was also investigated through X-ray diffraction and transmission electro microscopic. The results showed that α-Fe2O3 dopi ng reduced the transformation temperature of Al2O3, which can form stable α-Al2O3 phase at 900 ℃.

Key words: sol-gel, surface coating, Fe2O3-Al2 O3, composite
