Abstract:

In the water-in-oil microemulsion system of Triton X-100, 1-hexanol, cyclohexane and Fe(NO_3)_3 aqueous solution, α－Fe_2O_3 ultrafine particles were prepared by the method of precipitation using NH_3. From transmission electron micrographs the mean diameter of particles is about 3nm. The uniformity of particle is good. These result have been confirmed by the method of Mossbauer spectrum measurement. The conditions of preparation of α－Fe_2O_3 ultrafine particles could be controlled easily and the reaction medium could be used cyclically.

Key words: Microemulsion, Ultrafine particle, α-Fe2O3, Fe(NO3)3, Mossbauer spectrum
