Porcelain composition and winding-type coil component
Provided is a porcelain composition having sufficient magnetic permeability, flexural strength, and toughness, and having a high Curie temperature. Provided is a porcelain composition containing Fe, Cu, Ni, Zn, Co, and Cr, the porcelain composition containing 48.20 to 49.85 parts by mole of Fe in terms of Fe2O3, 2.00 to 8.00 parts by mole of Cu in terms of CuO, 11.90 to 18.70 parts by mole of Ni in terms of NiO, and 27.00 to 33.50 parts by mole of Zn in terms of ZnO when the total amount of Fe, Cu, Ni, and Zn in terms of Fe2O3, CuO, NiO, and ZnO is taken as 100 parts by mole. The Fe, Cu, Ni, and Zn are respectively converted into Fe2O3, CuO, NiO, and ZnO, and when the total amount of the Fe2O3, CuO, NiO, and ZnO is taken as 100 parts by weight, Co is contained in an amount of 5 ppm to 100 ppm in terms of CoO, and Cr is contained in an amount of 10 ppm to 400 ppm in terms of Cr2O3.
本发明提供具有充分的导磁率、抗折强度以及韧性且居里温度高的瓷器组合物。本发明提供一种瓷器组合物，含有Fe、Cu、Ni、Zn、Co以及Cr，将Fe、Cu、Ni以及Zn分别换算成Fe2O3、CuO、NiO以及ZnO，将上述Fe2O3、上述CuO、上述NiO以及上述ZnO的合计量设为100摩尔份时，含有换算成Fe2O3为48.20摩尔份～49.85摩尔份的Fe，换算成CuO为2.00摩尔份～8.00摩尔份的Cu，换算成NiO为11.90摩尔份～18.70摩尔份的Ni，换算成ZnO为27.00摩尔份～33.50摩尔份的Zn，将Fe、Cu、Ni以及Zn分别换算成Fe2O3、CuO、NiO以及ZnO，将上述Fe2O3、上述CuO、上述NiO以及上述ZnO的合计量设为100重量份时，含有换算成CoO为5ppm～100ppm的Co，换算成Cr2O3为10ppm～400ppm的Cr。
