Method for the Preparation of Soft Magnetic Ferrite Powder and Method for the Production of Laminated Chip Inductor

摘要

Provided are a method for producing a Ni-Cu-Zn ferrite powder having excellent sinterability at low temperature, and a method for producing a laminated chip inductor using the ferrite powder. A method for producing a soft magnetic ferrite powder containing Fe, Ni, Cu, and Zn as a main component, the method comprising the step of presenting an organic additive in a slurry containing a plasticizer and water of a raw material powder, wherein the organic additive includes a hydroxyl group and a carboxyl group A method for producing a soft magnetic ferrite powder, which is an organic compound having a compound thereof, a neutralized salt thereof or a lactone thereof, an organic compound having a hydroxymethylcarbonyl group, an organic compound having an enol hydroxyl group which can dissociate as an acid, or a neutralizing salt thereof.
