Abstract

The effects of Cu and Ti substitution on the sintering behavior, substitution mechanism, resistivity and dielectric properties of CuZn ferrites were investigated. Codoped Cu²⁺ and Ti⁴⁺ can effectively reduce the densification temperature of copper zinc ferrite to below 900 °C and improve the resistivity and dielectric properties. The copper and titanium-codoped CuZn ferrites and NiCuZn ferrites exhibited excellent compatibilities in physical and chemical matching during cofiring. Therefore, the copper and titaniumcodoped CuZn ferrites can be a good candidate material for an effective intermediate nonmagnetic layer for NiCuZn ferrites in preparing a multilayer chip inductor with a high rated current.
