Effect of Additives on Magnetic Properties of High Frequency MnZn Power Ferrite

  • Author Bio:

Abstract: The effect of additives, such as CaO and V2O5 on the magnetic properties of high frequency MnZn power ferrite is studied by the conventional ceramic process. As a result, the grain boundary resistivity increases and the power loss declines with the addition of CaO enriched at the grain boundary. By adding an optimum amount of V2O5 which acts indirectly via liquid phase formation and influences the microstructural development during sintering, the crystalline grain of ferrite was refined, the porosity decreases, the amount of grain boundary and the grain boundary resistivity increased, so the power loss is suppressed.
