Abstract

Very fine nickel powders starting from NiAl intermetallic compound by removing of aluminium from the lattice of NiAl intermetallics using a chemical processing were prepared. Powders with particle sizes up to 1 micron with high specific surface area were obtained. These powders can be used for applications in which a paste or smooth fine coating is needed, for example, in multilayer capacitors. Also, nickel coated graphite particles are employed for electromagnetic shielding. Very fine nickel powders with high surface area can be sintered together to make controlled porous structures for metal filters and electrode applications (batteries, fuel cells)..
