Processing of Metal Nanopowders for Novel Applications

摘要

The use of powders with a mean particle size less than 1μm is still considered to be advanced technology in powder metallurgy applications. Compared to ceramic processing, metal nanopowders are much more difficult to process and handle than powders in the micron size range. Nevertheless, wide ranging applications require metallic nanopowders and different production processes to serve this need. This paper provides an introduction to the different processes commercially used to produce metal nanopowders with specific emphasis on gas phase techniques for production of powders with low impurity levels. Example applications describe the state-of-the-art methods in using metal nanopowders commercially.
