摘要：

The lithium-zinc ferrite doped with Bi2O3 was prepared by the conventional oxide ceramic process. The effect of Bi2O3 on properties of lithium-zinc ferrite was investigated by means of characterizing the phase component and fracture surface micrograph by X-ray diffraction (XRD) and scanning electron microscope (SEM), density by Archimedean method, and magnetic properties by B - H analyzer. The results show that Bi2O3 can effectively bate the volatilization of lithium, promote solid state reaction and decrease the sintering temperature, but excessive Bi2O3 can restrain the crystal grain growth during sintering process. An optimal amount of Bi2O3 is beneficial to increase the saturation magnetic induction B-s and squareness B-r/B-s, and decrease the coercive force H-c of lithium-zinc ferrite.
