The influences of CZB(CaO-ZnO-B2O3 ) (CZB) glass addition on magnetic properties and structures of ferrite (Li0.45Zn0.3Ti0.2Mn0.03Mn0.03Fe1.99O4) prepared by the standard solid state reaction method was investigated.The results show that the sintering temperature of ferrites was reduced due to the induction of appropriate amount of CZB.X Ray Diffraction(XRD) and Scanning electron microscopy(SEM) analysis reveals that the glass phase doping has no effect on the structure of LiZn ferrite.Meanwhile,the grain size achieves a significant growth. The magnetic curve shows that the CZB can not only exhibit the maximal Bs at 0.25% but also low Hc values distinctly.With the increasing of CZB glass,the coercivity (Hc) decreases,reaching a minimum at 2.5% and then increases slightly.The solid phase reaction was promoted due to the key roles of the capillary pressure with few CZB glass addition.Doping small CZB glass,the solid phase reaction was also promoted.This could be attributed to a dominant diffusion effect in liquid.When the glass was added to excess,glass phase will obstruct the grain in growth so that anisotropy field was increased at the same time,in which a increase in Hc and △H and a decrease in Bs.The LiZn ferrite with CZB glass addition obtains well magnetic properties at sintering temperature of 910 ℃.As a result,this could apply to a design for phase shifter by using LTCC technology.
