High volume production of nanostructured materials
View Patent ↗A system and method for high volume production of nanoparticles, nanotubes, and items incorporating nanoparticles and nanotubes. Microwave, radio frequency, or infrared energy vaporizes a metal catalyst which, as it condenses, is contacted by carbon or other elements such as silicon, germanium, or boron to form agglomerates. The agglomerates may be annealed to accelerate the production of nanotubes. Magnetic or electric fields may be used to align the nanotubes during their production. The nanotubes may be separated from the production byproducts in aligned or non-aligned configurations. The agglomerates may be formed directly into tools, optionally in compositions that incorporate other materials such as abrasives, binders, carbon-carbon composites, and cermets.
1. An apparatus for manufacturing nanostructure material, the apparatus comprising:
a catalyst feeder for introducing metal catalyst feed material into the apparatus;
a nano-element feeder for introducing nano-element feed material into the apparatus;
a vaporizer having a heat source selected from the group consisting of (a) a microwave plasma generator and (b) a hollow cathode glow discharge system, the vaporizer (i) to form metal catalyst vapor from the metal catalyst feed material and (ii) to establish atomic nano-element from the nano-element feed material;
a condenser comprising a condensation region for condensing the metal catalyst vapor into metal catalyst particles and for consolidating the atomic nano-element into nano-element nano-particle clusters and comprising an aggregation region for aggregating the metal catalyst particles and the nano-element nano-particle clusters as metal nano-element agglomerates.
2. The apparatus of claim 1 wherein the catalyst feeder and the nano-element feeder are combined as one apparatus for feeding a mixture of metal catalyst feed material and nano-element feed material into the apparatus.
