FERRITE SINTERED BODY, FERRITE SINTERED PLATE, AND FERRITE SINTERED SHEET
An object or technical task of the present invention is to provide a ferrite sintered sheet having a dense ferrite microfine structure which has a large µ ' value, a small µ " value, and a small temperature-dependent change of the µ ' value thereof. The present invention relates to a ferrite ceramics having a composition comprising 47.5 to 49.8 mol% of Fe 2 O 3 , 13.5 to 19.5 mol% of NiO, 21 to 27 mol% of ZnO, 7.5 to 12.5 mol% of CuO and 0.2 to 0.8 mol% of CoO, all of the molar amounts being calculated in terms of the respective oxides, the ferrite ceramics further comprising 0.2 to 1.4% by weight of SnO 2 and 0.005 to 0.03% by weight of S and having a density of 5.05 to 5.30 g/cm 3 ; and a ferrite sintered sheet comprising the ferrite sintered plate on a surface of which a groove or grooves are formed, and an adhesive layer and/or a protective layer formed on the ferrite sintered plate.
