Patent ID: 8092571

Claim:
A synthesis apparatus for nanopowders, comprising: (a) a combustion reactor for nanopowders that comprises: (i) an oxidized gas supply nozzle connected to an oxidized gas tube, (ii) a gas supply unit provided with a fuel gas tube and a precursor gas tube, and (iii) a reaction nozzle forming concentricity on an inner wall of the oxidized gas supply nozzle, the reaction nozzle being connected to the gas supply unit and having an inlet opening for supplying oxidized gas disposed at a region adjacent to a jet orifice for spraying flames; (b) an oxidized gas controller for controlling the flow rate of an oxidized gas supplied to an oxidized gas tube; (c) a fuel gas controller for controlling the flow rate of a fuel gas supplied to a fuel gas tube; (d) a precursor gas controller for controlling the flow rate of a precursor gas supplied to a precursor gas tube; and (e) a vaporizer mounted in an oil bath and connecting the precursor gas controller and the precursor gas tube, and vaporizing a precursor in a liquid state into a precursor gas.
