| Abstract: |
| Hydrophilic nanometer magnetic Fe3O4 was made by chemical co-precipitation method, after repeatedly washing, filtering, airing and drying, the magnetic nano-particle Fe3O4 was obtained, the experimental products under different experiment conditions were analyzed, when the proportion of the reactants of ferrous ion, iron ion and hydroxide ion were 1 mol:2 mol:8 mol, the optimal conductivity and magnetism of the nano-particle Fe3O4 was received.
