Abstract：
 The invention takes ferric ion salt as raw material, which is taken solvent thermal reaction under 200-300deg.C to form Fe3O4 nanometer magnetic bead. At same reaction condition, through adding one or more kind of divalent soluble metal ion salt to make reaction with ferric ion salt and controlling the level of addition, the mol ration between the divalent soluble metal ion salt and ferric ion, the ferrite nanometer magnetic bead and the compound ferric ion nanometer magnetic bead are formed.
