Abstract
A method for stabilizing magnetic metal particles includes the steps of: (a) subjecting the magnetic metal particles to a reduction reaction; (b) isolating the reduced magnetic metal particles from air and dipping them in an organic solvent; (c) allowing the organic solvent to vaporize slowly in air, thereby forming oxidized layers on the magnetic metal particles; and (d) mixing the magnetic metal particles in step (c) with a titanate coupling agent solution to form absorbed layers of a titanate coupling agent on the surfaces of the magnetic metal particles.
