Abstract:
1. An apparatus for producing a multi-component nanopowders, said apparatus comprising: a reaction chamber comprising a cavity that includes a reaction zone; one or more reactant inlets for introducing a plurality of precursors into said reaction chamber whereby said precursors produce a multi-component precursor flux that forms a particle stream through said reaction zone; at least two precursor sources that introduce precursors into said reaction chamber through said one or more reactant inlets such that each individual precursor flux can be independently controlled so that the composition of the multi-component precursor flux can be varied with time; a heater able to heat reaction zone to a temperature of at least about 800° C.; and a spatially addressable collector deposits different nanopowders at different locations on a substrate wherein said spatially addressable collector comprises a cyclone particle trap.
