Abstract
Provided are non-magnetic nickel powders and a method for preparing the same. The nickel powders have non-magnetic property and a HCP crystal structure. The method include (a) dispersing nickel powders with a FCC crystal structure in an organic solvent to prepare a starting material dispersion, and (b) heating the starting material dispersion to transform the nickel powders with the FCC crystal structure to the nickel powders with the HCP crystal structure. The nickel powders do not exhibit magnetic agglomeration phenomenon. Therefore, the pastes for inner electrode formation in various electronic devices, which contain the nickel powders of the present invention, can keep the well-dispersed state. Also, inner electrodes made of the nickel powders can have a low impedance value even at high frequency band.
