Patent ID: 8641873

Claim:
A method for synthesizing nano particles, comprising: moving material in a plasma generating space of a plasma generator in a first direction; synthesizing nano particles by cooling the material moved along the first direction through a cooler, wherein the synthesizing the nano particles may be performed by cooling the material at temperatures which become lower as the material moves in the first direction, and the synthesizing the nano particles includes decelerating the moving velocity of the material by injecting decelerating gas, from a deceleration gas supplier facing opposite to the plasma generator, in a second direction opposite to the first direction, the plasma generator, the cooler, and the deceleration gas supplier being disposed on a same line in a row; and recovering the synthesized nano particles into a recovery device after changing the moving direction of the nano particles in a third direction perpendicular to the first direction, the recovery device being disposed at one side of the cooler between the plasma generator and the deceleration gas supplier.
