Abstract
Official abstract text for this publication.
A ferrite composition includes a main component and an accessory component. The main component includes 18 to 30 mol % of iron oxide in terms of Fe 2 O 3 , 4 to 14 mol % of copper oxide in terms of CuO, 0 to 6 mol % of zinc oxide in terms of ZnO, and a remaining part of nickel oxide. The accessory component includes 0.30 to 1.83 pts.wt. of silicon compound in terms of SiO 2 , 2.00 to 10.00 pts.wt. of cobalt compound in terms of Co 3 O 4 , and 1.00 to 3.00 pts.wt. of bismuth compound in terms of Bi 2 O 3 with respect to 100 pts.wt. of the main component. A cobalt compound content in terms of Co 3 O 4 divided by a silicon compound content in terms of SiO 2 is a value of 5.5 to 30.0.
First claim
Opening claim text (preview).
The invention claimed is: 1. A ferrite composition comprising a main component and an accessory component, wherein the main component includes: 18.0 to 30.0 mol % of iron oxide in terms of Fe 2 O 3 ; 4 to 14 mol % of copper oxide in terms of CuO; 0 to 6.0 mol % of zinc oxide in terms of ZnO; and a remaining part of nickel oxide, the accessory component includes: 0.30 to 1.83 pts. wt. of silicon compound in terms of SiO 2 ; 4.00 to 10.00 pts. wt. of cobalt compound in terms of Co 3 O 4 ; and 1.00 to 3.00 pts. wt. of bismuth compound in terms of Bi 2 O 3 with respect to 100 pts. wt. of the main component, and a cobalt compound content in terms of Co 3 O 4 divided by a silicon compound content in terms of SiO 2 is a value of 5.5 to 30.0. 2. An electronic device comprising a ferrite sintered body composed of the ferrite composition according to claim 1 .
