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(Ba_0.9Bi _0.1O)·2(Co_0.8Cu_0.2O)·12(Fe _1.975Zn_0.025O₃) 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.
