Bi 2 O 3 Addition Effects on the Sintering Mechanism, Magnetic Properties, and DC Superposition Behavior of NiCuZn Ferrites
Source abstract
Abstract
The Bi 2 O 3 addition effects on the densification mechanism, magnetic properties, and DC superposition behavior of NiCuZn ferrites are investigated in this study. Bi 2 O 3 addition can effectively promote NiCuZn ferrite densification. The densification controlling mechanism is dominated by the liquid formation resulting from the Bi 2 O 3 and Bi 2 CuO 4 eutectic reaction as Bi 2 O 3 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 Bi 2 O 3 to adjust the nonmagnetic copper and bismuth‐rich precipitate thickness at the grain boundaries.
