Abstract

Disclosed are a large-scale composite synthesis system, a reactor therefor, and a synthesis method using the same, wherein two or more different samples are vaporized in respective vaporizers, and are then fed into a reactor that has a relatively large transverse cross-sectional diameter compared to the connector for transporting the samples in a gas phase and is maintained at a temperature lower than that of the connector, thus producing a powder composite, the composite being synthesized while being electrostatically attached to an adherend surface.

First claim

What is claimed is:

a second heater for heating the second vaporizer;
a connector for connecting the first vaporizer and the second vaporizer to a reactor; and
the reactor that receives the first sample and the second sample respectively vaporized in the first vaporizer and the second vaporizer so as to synthesize a composite,
wherein the reactor has a relatively large transverse cross-sectional diameter compared to the connector, and is maintained at a temperature lower than a temperature of the connector, and
the first sample and the second sample in a gas phase are instantly dispersed due to a pressure difference and a temperature difference when being fed into the reactor from the connector, thereby producing a powder composite, and the powder composite is synthesized while being electrostatically attached to an adherend surface,
wherein the adherend surface comprises a plate made of a vitreous material or a metal plate provided at a lower portion of the reactor, and
the powder composite is electrostatically attached to the plate made of a vitreous material or the metal plate, and
wherein a filter made of quartz or a carbon material is further provided at a lower portion of the reactor, and the plate made of a vitreous material or the metal plate is disposed on the filter.

2. The composite synthesis system of claim 1 , wherein the metal plate comprises any one selected from among aluminum, nickel, silicon, and aluminum-based alloys containing at least one selected from nickel, magnesium, iron, silicon, and sulfur elements.

3. The composite synthesis system of claim 1 , wherein the transverse cross-sectional diameter of the reactor is equal to or greater than 15 times a diameter of the connector.

4. The composite synthesis system of claim 1 , wherein a heating furnace is further provided around the reactor, and an inside of the reactor is maintained at 60° C. or less.

5. The composite synthesis system of claim 1 , wherein the connector is further provided with a heating line for heating the first sample and the second sample in a gas phase, which are transported to the reactor via the connector, and an inside of the connector is maintained at 60 to 250° C.

6. The composite synthesis system of claim 1 , wherein the reactor further comprises a reactive gas supplier for supplying a reactive gas necessary for reaction of the first sample and the second sample.

7. The composite synthesis system of claim 1 , wherein the adherend surface further comprises an entire inner wall of the reactor made of a vitreous material or a metal material.

8. The composite synthesis system of claim 1 , further comprising a recycler for re-supplying exhaust gas, discharged from the reactor, to the reactor.

9. The composite synthesis system of claim 1 , wherein the first vaporizer or the second vaporizer comprises:
a main body part that receives a sample;
a sample supply part formed at one side of the main body part so as to supply the sample;
a gas supply part formed at one side of the main body part so as to supply a gas for vaporizing the sample; and
a discharge part formed at an upper portion of the main body part so as to discharge the vaporized sample.

10. A reactor for a composite synthesis system, comprising:
a feed section connected to a connector through which a first sample and a second sample in a gas phase pass so as to receive the first sample and the second sample in a gas phase;
a main body having a relatively large transverse cross-sectional diameter compared to the connector and maintained at a temperature lower than a temperature of the connector, wherein the first sample and the second sample in a gas phase are instantly dispersed due to a pressure difference and a temperature difference when being fed from the connector, so that a production reaction of a powder composite occurs, and the powder composite is electrostatically attached to an adherend surface; and
a discharge section for discharging exhaust gas after the production reaction of the powder composite,
wherein the adherend surface comprises a plate made of a vitreous material or a metal plate provided at a lower portion of the main body, and the powder composite is electrostatically attached to the plate made of a vitreous material or the metal plate, and
wherein a filter made of quartz or a carbon material is further provided at a lower portion of the main body, and the plate made of a vitreous material or the metal plate is disposed on the filter.

11. The reactor of claim 10 , wherein the metal plate comprises any one selected from among aluminum, nickel, silicon, and aluminum-based alloys containing at least one selected from nickel, magnesium, iron, silicon, and sulfur elements.
