ABSTRACT:
A ferrofluid comprised of composite particles comprised of polymer-enmeshed magnetic metallic particles in indefinite suspension in a carrier fluid is produced by providing a pair of electrodes formed of a composition which will produce the desired magnetic metallic particles, immersing the electrodes in an organic dielectric liquid, applying a pulsed electric potential between the electrodes, adjusting the gap therebetween until there is an electric discharge eroding an electrode producing magnetic metallic particles enmeshed in polymer, recovering the magnetic material from the dielectric liquid and dispersing the magnetic material in a carrier fluid producing ferrofluid.
