Title:
METHOD FOR PREPARING NON-FERROUS METAL NANOPOWDER BY ELECTRICAL EXPLOSION PROCESS
Document Type and Number:
WIPO Patent Application WO/2008/071067
Kind Code:
A1
Abstract:
Processing technique of metal nanopowders, particularly preparation of non-ferrous metal nanopowders by electrical explosion method, including supplying high current to energize metal wire in inert gas, melting and exploding it into metal nanosize particles. The method has low cost, reduces power consumption, and produces less pollution. The result shows that the invention particle shape is spheral, and has larger specific surface area and good liquidity.
