  • Arc reactor and process for producing nanoparticles
    Patent number: 10022697
    Abstract: An arc reactor and a process for the production of nanoparticles are disclosed. The reactor has a crucible in a gas-tight housing having a carrier gas inlet and a spaced-apart carrier gas outlet. The carrier gas inlet is directed to the side of the crucible opposite the crucible opening. The inlet can be disposed below the crucible and directed to the side of the crucible opposite the crucible opening. The carrier gas outlet is disposed above the crucible and exits the housing above the crucible. The carrier gas outlet is formed by a hood disposed at a distance above the crucible, which is separated from the crucible and formed by an exhaust pipe that connects the hood to the carrier gas outlet of the housing. The reactor housing has at least one inlet for cooling gas. This can be directed at an interstice formed between the crucible and the hood.
