PURPOSE:To provide nonmagnetic Fe2O3+ZnFe2O4 combined ceramics used for a magnetic head and less liable to chipping at the time of working because of satisfactory workability. CONSTITUTION:One or more among Y2O3, La2O3, CeO2, Al2O3, ZrO2 and TiO2, as secondary components are added to ceramics having a combined structure consisting of Fe2O3 and ZnFe2O4 phases by, 0.01-5wt.% basing on 100 pts.wt. of the ceramics to obtain the objective nonmagnetic ceramics for a magnetic head. |
