Abstract
A method and system for synthesizing nanocrystalline material. A system includes a chamber, a nonconsumable cathode shielded against chemical reaction by a working gas not including an oxidizing gas, but including an inert gas, a consumable anode vaporizable by an arc formed between the cathode and the anode, and a nozzle for injecting at least one of a quench and reaction gas in the boundaries of the arc.
Claims6
An article of manufacture, comprising:
- a nanocrystalline composite comprising a first nanocrystalline material comprising discrete primary particles having a size of about 1-50 nm and an average size less than about 40 nm blended with a second nanocrystalline material comprising discrete primary particles having a size of about 1-50 nm and an average size less than about 40 nm, each of said primary particles having a substantially spherical shape wherein said discrete primary particles are formed within the boundaries of an ionized arc extending between a consumable anode and a nonconsumable cathode.
