80 or more being possessed with the magnetic oxide sintering body, and the high frequency circuit

摘要

PROBLEM TO BE SOLVED: To provide a sintered magnetic oxide which can be baked at 1000°C or below, especially around 900°C, is high in electric resistivity, low in permittivity, and contains Y-type hexagonal ferrite as the main component ferrite and a high-frequency circuit part using the same.;SOLUTION: This sintered magnetic oxide contains Y-type hexagonal ferrite of 80% or above. The sintered magnetic oxide contains 3 to 15 mol% cobalt oxide in terms of CoO, 5 to 17 mol% copper oxide in terms of CuO, 57 to 61 mol% iron oxide in terms of Fe₂O₃, and residual mol% AO (AO is either BaO or SrO) as main components and 0.6 to 7 wt.% borosilicate glass, boron zinc silicate glass, or bismuth glass oxide as an auxiliary component.;COPYRIGHT: (C)2002,JPO
