Abstract:
      The high permeability Mn-Zn ferrites doped CaO-Bi2O3-MoO3-xNb2O5(x= 0.000- 0.075wt%,step:0.015) were prepared by high temperature solid state reactions. The phase composition, microstructure and electrical and magnetic properties were measured by XRD, SEM, FPP, impedance analyzer and soft magnetic AC testing system. The effects of Nb2O5on the Microstructure and magnetic properties of Mn-Zn ferrites were investigated. The results showed that Nb2O5 can refine the microstructure, improve the density, frequency stability and quality factor, electrical resistivity and reduce specific losses when a small amount of doping Nb2O5 are added. Nb2O5 would result in the deterioration of microstructure and the electromagnetic properties of the Mn-Zn ferrites when a large amount of doping Nb2O5 is added. When the Nb2O5 doping amount is 0.030wt%, the best comprehensive performance of Mn-Zn ferrites were obtained.
