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
