MnZn-based ferrite sintered body and method for producing MnZn-based ferrite
A MnZn-based ferrite sintered body having low magnetic core loss in a wide temperature range, in particular in a low temperature range of 60 DEG C or less, which contains a main component and an auxiliary component, the main component being composed of 53.5-54.3 mol% Fe in terms of Fe2O3, 4.2-7.2 mol% Zn in terms of ZnO, and the remainder being Mn in terms of MnO, and the auxiliary component being composed of Fe in terms of Fe2O3, Zn in terms of ZnO, and Mn in terms of MnO. The auxiliary component is composed of 0.003-0.018 parts by mass of Si in terms of SiO2, 0.03-0.21 parts by mass of Ca in terms of CaCO3, 0.40-0.50 parts by mass of Co in terms of Co3O4, 0-0.09 parts by mass of Zr in terms of ZrO2, and 0-0.015 parts by mass of Nb in terms of Nb2O5 relative to 100 parts by mass of the total of the main components, the content ratio of Zn to Co is 9.3-16.0, and the maximum magnetic core loss at 23-100 DEG C is 1000 kW/m3 or less.
一种宽温度范围、特别是在60℃以下的低温度域磁芯损耗低的MnZn系铁氧体烧结体，其含有主成分和副成分，主成分由以Fe2O3换算53.5～54.3摩尔％的Fe、以ZnO换算4.2～7.2摩尔％的Zn和以MnO换算剩余部分的Mn构成，副成分由相对于主成分合计100质量份以SiO2换算0.003～0.018质量份的Si、以CaCO3换算0.03～0.21质量份的Ca、以Co3O4换算0.40～0.50质量份的Co、以ZrO2换算0～0.09质量份的Zr和以Nb2O5换算0～0.015质量份的Nb构成，Zn与Co含量比为9.3～16.0，23～100℃的磁芯损耗最大值为1000kW/m3以下。
