Abstract�� In this work,nanometer magnetite(Fe_3O_4) particles were prepared by chemical co-precipitation,NH_3��H_2O was chosen as precipitating agent,and was added to the mixed aqueous solution containing ferric and ferrous ions to produce nanometer Fe_3O_4 particles.Some influence factors on the size and characteristic of the product were investigated,and preliminary characterization was also performed.
