Apparatus for producing nano-particles according to the present invention may comprise a furnace defining a vapor region therein. A precipitation conduit having an inlet end and an outlet end is positioned with respect to the furnace so that the inlet end is open to the vapor region. A quench fluid supply apparatus supplies quench fluid in a gas state and quench fluid in a liquid state. A quench fluid port positioned within the precipitation conduit is fluidically connected to the quench fluid supply apparatus so that an inlet to the quench fluid port receives quench fluid in the gas state and quench fluid in the liquid state. The quench fluid port provides a quench fluid stream to the precipitation conduit to precipitate nano-particles within the precipitation conduit. A product collection apparatus connected to the outlet end of the precipitation conduit collects the nano-particles produced within the precipitation conduit. While prior art methods for producing nano-particles represented complicated and expensive ways for producing minute quantities of nano-particles, using the method of the present invention, nano-particles of the desired size and composition can be produced continuously on a commercial scale at low cost.
