US Patent 7182801 - Non-magnetic nickel nanoparticles

Nickel powders are useful in forming a variety of electronic circuit devices including the electrodes for multilayer ceramic capacitors. However, the powders tend to clump together based on their magnetic properties which causes difficulty in fabrication. This patent from Samsung teaches how to form nickel nanopowders that are non-magnetic to avoid such difficulties. Claim 1 reads:

1. Non-magnetic nickel powders having an hexagonal close packed (HCP) crystal structure wherein the average particle size of said non-magnetic nickel powders is in the range of 30 to 800 nm.
