Abstract
A process for producing nanoscale powders, and the powders so produced. The process comprises mixing an emulsion comprising all of the elements of the desired powder composition and a combustible fuel, and then combusting that emulsion to produce a powder. Powders with a median particle size of less than 50 nm have been made by this process. The process is suitable for the production of many types of powders, including particles and nanowhiskers of simple, doped, and polymetallic powders.
Claims13
A process for producing fine powders of a selected composition, comprising
- forming a liquid emulsion comprising precursor elements of the selected composition and a combustible fuel;
- combusting the emulsion to cause the precursor elements to combine to form a powder of the selected composition;
- and
- collecting the powder formed.
