Abstract

The magnetic characteristics of Mg-Zn ferrite that was fired at $1150^{\circ}C$ for 1hour and sintered at $1250^{\circ}C$ for 3hours was examined. The composition ratio of the ferrite was changed after sintering. In that case the composition ratio of ${Fe_2}{O_3}$ was increased but that of CuO was decreased. When the addition quantity of CuO was 3.8 mole%, it's shrinkage rate had maximum value. Magnetic permeability was decreased as the addition rate of CuO was increased and MgO was decreased. When the composition rate of CuO was 2.3 mol% and MgO was 10.9 mol%, the firing density had maximum value. In case that CuO was 2.8mol% and MgO was 10.4mol%, PL had minimum value.
