Abstract
Provided are non-magnetic nickel powders and a method for preparing the same. The nickel powders are non-magnetic and have a HCP crystal structure. An exemplary method includes (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 or aggregation phenomenon. Therefore, exemplary pastes for inner electrode formation in various electronic devices, which contain the nickel powders of the present disclosure, can be provided in a relatively uniform, well-dispersed state because of the reduced aggregation and agglomeration of the nickel powder. Also, inner electrodes made of the nickel powders can have a low impedance value even at high frequency band.
