Abstract

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.
