FERRITE CERAMIC COMPOSITION, CERAMIC ELECTRONIC COMPONENT, AND PROCESS FOR PRODUCING CERAMIC ELECTRONIC COMPONENT

摘要

This disclosure provides a ferrite ceramic composition, a ceramic electronic component including the ceramic composition, and a process of producing a ceramic electronic component including the ferrite ceramic composition, of which the insulation performance can be secured even when fired simultaneously with a metal wire material containing Cu as the main component, and which can have good electric properties. The ferrite ceramic composition includes an Ni—Mn—Zn-based ferrite having a molar content of CuO of 5 mol % or less and in which, when the molar content (x) of Fe2O3 and the molar content (y) of Mn2O3 are expressed by a coordinate point (x,y), the coordinate point (x,y) is located in an area bounded by coordinate points A (25,1), B (47,1), C (47,7.5), D (45,7.5), E (45,10), F (35,10), G (35,7.5) and H (25,7.5).

1. A ceramic electronic component comprising a magnetic body part and a metal wire material embedded in the magnetic body part,
wherein the metal wire material comprises an electrically conductive material containing Cu as the main component and the magnetic body part comprises a ferrite ceramic composition comprising at least Fe, Mn and Zn, wherein, in the ferrite ceramic composition, a molar content of Cu is 0 to 5 mol % in terms of CuO content and, when a molar content (x (mol %)) of Fe in terms of Fe2O3 content and a molar content (y (mol %)) of Mn in terms of Mn2O3 content are expressed by a coordinate point (x,y), the coordinate point (x,y) is located in an area bounded by coordinate points A (25,1), B (47,1), C (47,7.5), D (45,7.5), E (45,10), F (35,10), G (35,7.5) and H (25,7.5).
