ABSTRACT:Crystalline powder of y-AlzO, has been successfully synthesized by employing aluminum acetylacetonatcmethanol-ethylene glycol-water system via a novel sol-gel roule. The crystalline particles of the powder obtained were examined by X-ray diffraction, scanning electron microscopy and transmission electron microscopy, while the surface area of the oxide powder was obtained by nitrogen adsorption BET surface area measurement. The result obtained indicated that the y -Alz03 is cubic with a = b = c = 7.5911 A 0, the mean particle diameter is 85 nm and the BET surface area is 120 m2/g. The result showed that the product obtained is a pure y -Al20l with a nanocrystalline structure. The oxide powder could be very important in catalysis and gas sensing of hydrocarbons.
