The results of investigations on fine dispersion of rare-earth elements on pre-crushed oxides by electrical discharges in aquatic environment are given. A possibility of obtaining oxide particles with a size less than one micrometer is shown, including from large blocks of previously coagulated oxide particles. A feasibility is shown of choosing such an interposition of zones generating pressure waves and pulsed hydraulic currents, at which local regions of intense electric-discharge cavitation arise, providing dispersion. A concept of an efficient electric discharge dispersing chamber is proposed.
