Abstract：
 This invention discloses a method for preparing nanometer particulates of Fe304. It is characterized by: arc discharging is used, with self-consumption of pure iron anode proceeded in water medium to produce nanometer particulates of Fe304. This inventive Fe304 magnetic nanometer particulates are of spherical with even size, having various kinds of excellent properties. The raw material of this invention is industrial pure iron rod, being of easily available, low cost, the advantages of this inventive method are: simple equipment, controllable process parameters, continuous and in large scale production.
