The Bi2O3-B2O3-ZnO-SiO 2 (BB35SZ) glass effects on the sintering behavior and magnetic properties of Bi-Zn co-doped Co2Y ferrites were investigated in developing low-temperature-fired ferrites. The results indicate that BB35SZ glass can be used as a sintering aid to reduce the densification temperature of Co2Y ferrites from 1300°C to 900°C. The 2(Ba 0.9Bi0.1O)·2(Zn0.4Co 0.4Cu0.2O)·6(Fe1.97Zn 0.03O3) ferrite with 4 wt% BB35SZ glass can be densified below 900°C, exhibiting an initial permeability of 3.4 and quality factor of 55. This process provides a promising candidate for multilayer chip magnetic devices for microwave applications.
