Abstract
Official abstract text for this publication.
Metal powder has composite particles each coated with a Zn-based ferrite film not containing Ni.
First claim
Opening claim text (preview).
What is claimed is: 1. Metal powder comprising: composite particles that are metal magnetic particles each coated with a Zn-based ferrite film essentially free of Ni, the Zn-based ferrite film being coated with a Ni—Zn ferrite film. 2. The metal powder according to claim 1 , wherein the Zn-based ferrite film is formed on a surface of each of the metal magnetic particles by plating, the metal magnetic particles being permalloy particles. 3. The metal powder according to claim 1 , wherein the Zn-based ferrite film is insulating ferrite having a composition shown as Zn x Fe 3-x O 4 , wherein x is equal to or greater than 0.15 and less than 1. 4. The metal powder according to claim 1 , wherein the Zn-based ferrite film does not contain Ni. 5. An electronic component comprising: a body containing a metal powder, the metal powder comprising composite particles that are metal magnetic particles each coated with a Zn-based ferrite film essentially free of Ni, the Zn-based ferrite film being coated with a Ni—Zn ferrite film; and an inductor provided in or on the body. 6. The electronic component according to claim 5 , wherein the body is made of a mixture of the metal powder and a ferrite magnetic material. 7. The electronic component according to claim 5 , wherein the body is made of a mixture of the metal powder and glass, or a mixture of the metal powder and resin.
