Patent ID: 6843968

Claim:
A apparatus for manufacturing a liquid medium containing composite ultrafine particles, comprising: a first chamber having an inlet and outlet in which dispersion medium introduced and removed, and said dispersion medium consisting a liquid medium in which ultrafine particles of different materials from each other are dispersed; a second chamber having an inlet and outlet which said dispersion medium is introduced and removed; an aggregating/bonding means having two nozzle sections electrically separated each other for introducing said dispersion medium communicating within said first and second chambers, injecting these dispersion media and crossing/crashing each other; a high frequency source for applying a high frequency voltage to said dispersion medium communicating within said first and second chambers through an insulating member that high frequency is capable of being transmitted; and a direct current source connected to a member located up to said nozzle section on the downstream side in a flow direction of said dispersion medium than the application position of said high frequency voltage.
