Abstract

The Bi2O3B2O3ZnOSiO2 (BB35SZ) glass effects on the sintering behavior and microwave magnetic properties of CuBiZn co-doped Co2Z ferrites were investigated to develop low-temperature-fired ferrites. The glass wetting characteristics on the Co2Z ferrite surface, X-ray diffractometer, scanning electron microscopy and a dilatometer were used to examine the BB35SZ glass effect on Co2Z ferrite densification and the chemical reaction between the glass and Co2Z ferrites. The results indicate that BB35SZ glass can be used as a sintering aid to reduce the densification temperature of Co 2Z ferrites from 1300 to 900 °C. 3(Ba0.9Bi 0.1O)·2(Co0.8Cu0.2O)·12(Fe 1.975Zn0.025O3) ferrite with 2 wt% BB35SZ glass can be densified below 900 °C, exhibiting an initial permeability of 3.4. This process provides a promising candidate for multilayer chip magnetic devices for microwave applications.
