Abstract(English):

The invention discloses a high-frequency low-magnetic-loss Mn-Zn ferrite material, which comprises the following raw materials, by weight part, 100 parts of a main component, 0.06-0.12 parts of an auxiliary component, and 1.5-2.5 parts of polyvinyl alcohol. The main component comprises, by mole part, 25-35 parts of ZnO, 10-20 parts of MnO, and 30-50 parts of Fe2O3, and the auxiliary component comprises, by weight part, 8-16 parts of V2O5, 20-35 parts of ZrO2, 6-12 parts of Cr2O3, 4-10 parts of B2O3, 6-12 parts of SnO, 20-30 parts of TiO2, 6-10 parts of Co2O, 25-55 parts of WO2, and 25-45 parts of CaCO3. The Mn-Zn ferrite material is good in thermal stability, high in resistivity, and low in magnetic loss and has high-frequency high-saturation flux density.
