PURPOSE:To increase permeability by adding CaO and SiO2 as secondary components to a base consisting of Fe2O3, ZnO and MnO2 contg. specified amts. of P and Cl. CONSTITUTION:Starting material contg. 0.01-0.15wt.% CaO and =0.02wt.% SiO2 besides a base consisting of 51.0-54.0mol% Fe2O3 contg. =0.05wt.% P and 0.01-0.12wt.% Cl, 19.0-25.0mol% ZnO and the balance MnO is calcined and pulverized. The resulting mixed powder is compression-molded into a prescribed shape and sintered in an oxidizing atmosphere to obtain a magnetic core of Mn-Zn ferrite having =10,000 initial permeability at 10kHz.
