I heard there is a hydrothermal method for the fabrication of micro size Fe3O4 particles. But it is hard to find a good protocol to follow. Is there anyone experienced on it? Thanks!
Yes, generally use FeCl2·4H2O and FeCl3·6H2O as materials to synthesize magnetic Fe2O3 namo paritcles by hydrothermal method. There are so many papers written in Chinese and in English, you can download to read them. In addition, there are other method to synthesize, i.e., hydrolysis method and solid phase method.
