The Bi2O3 addition effects on the densification mechanism, magnetic properties, and DC superposition behavior of NiCuZn ferrites are investigated in this study. Bi2O3 addition can effectively promote NiCuZn ferrite densification. The densification controlling mechanism is dominated by the liquid formation resulting from the Bi2O3 and Bi2CuO4 eutectic reaction as Bi2O3 addition is increased above 2wt%. A suitable compromise between the initial permeability and DC-bias superposition characteristic can be obtained by adding a proper amount of Bi2O3 to adjust the nonmagnetic copper and bismuth-rich precipitate thickness at the grain boundaries.
