HOU HAIBIN / XUE WEI / WANG LIANG / LIU ZHIJIAN / WEI XIAODONG

The invention provides a manganese-zinc ferrite composite material and a preparation method thereof. The manganese-zinc ferrite composite material comprises a magnetic core and a metal oxide coating coated on the surface of the magnetic core, and the magnetic core is made of manganese-zinc ferrite; and the metal oxide coating is made of iron oxide, zinc oxide, nickel oxide and a fluxing agent. According to the manganese-zinc ferrite composite material and the preparation method thereof provided by the embodiment of the invention, the metal oxide coating on the surface of the manganese-zinc ferrite composite material has high adhesive force and high density, and the surface resistance of a manganese-zinc ferromagnetic core can be effectively improved.
