Effects of Compounding Addition of Sintering Aids on DC Bias Superposition Characteristic of NiCuZn Ferrites

NiCuZn ferrites were prepared through conventional solid-state method. The effects of the sintering aids such as Bi2O3 and glass on the DC bias superposition characteristic of NiCuZn Ferrites were investigated. It was apparently discovered that when the glass and the Bi2O3 were doped together, the grain size was distributed consistently and the DC bias superposition characteristic reached an achievement comparing to the situation when the Bi2O3 and glass were doped alone. Additionally, it was also observed that the DC bias superposition characteristic had a significant relationship with Hc and △B.
