Abstract:
1. A method of manufacturing a liquid medium containing composite ultrafine particles, said method comprising the steps of: preparing a dispersion medium that is a liquid medium in which ultrafine particles comprising different materials from each other are dispersed; introducing said dispersion medium into a first electrically conductive chamber and a second electrically conductive chamber having an inlet and an outlet with a high pressure, respectively; applying high frequency voltage to said first and second electrically conductive chambers, respectively, excite each dispersion medium communicating within the first and second electrically conductive chambers, respectively; applying direct current voltage to each excited dispersion medium on a portion of each of the chambers which is located a downstream side than an application position of said high frequency voltage to electrify each dispersion medium in different polarities from each other; and injecting said dispersion medium electrified in different polarities from each other through two nozzle sections electrically separated from each other at a high speed, respectively to cross and crash with each other, thereby aggregating and bonding through excitation transfer as well as electrostatically aggregating ultrafine particles with each other in said liquid medium in a crashing filed.
