The 25%Bi2O3-30%B2O3-10%SiO2-35%ZnO (molar ratio, abbreviated as BBSZ) glass were successfully prepared by solid-phase method. The amount of BBSZ glass varied from 1wt% to 5 wt% was optimized and its effects on the sintering behavior, structure and magnetoelectric properties of the Co / Ti doped M-type barium ferrite were investigated by HP 4291B vector analysis, scanning electron microscopy (SEM) and VSM magnetometer respectively. The testing results show that the ferrite could be well sintered at 900°C with excellent performances when the 3wt% BBSZ is added. The initiative permeability and cut-off frequency are 13.5 and 800MHz, respectiveley, which suggests that this material is a candidate for application in the fabrication of chip inductors by the technology of low temperature cofired ceramics and ferrites (LTCC).
