| Abstract: | Ultrafine particles will be a most significant material in the 21st century. Monodispersed hematite nanoparticles have a wide use in the world. More and more attention will be drawn to their study. The methods for preparation of ferric hydrous oxide solutions (consisting of particles uniform in shape of narrow size distribution) are described in detail. The final outcome of the hydrolysis and uniform precipitation process depends on ferric ions, temperature, time of aging, the nature of the anions present etc. In summary, the shape and size of the particles depend on the environmental conditions during the process. The particles are characterized by TEM and XRD. In this experiment, we give some improvement, such as simplified experiment conditions and greatly improve the yield |
