| titleOfInvention | Method for preparing MnZn ferrite |
| abstract | The invention relates to a method for preparing MnZn ferrite. The method comprises the following steps of: carrying out reflux conversion by using ammonium bicarbonate and ammoniacal liquor as precipitating agents, carrying out coating modification by compounding silane and a titanate coupling agent before moulding to prepare an MnZn ferrite nanometer powder with a monoatomic coating, utilizing good reactivity between hydrolysable groups of a coupling agent and the surface of the nanometer powder; adding an organic binder; allowing other atoms in the coupling agent to form a gas and volatilize during the subsequent sintering process with Si<4+> and Ti<4+> left in MnZn ferrite, and raising grain boundary resistance at enriched crystal boundary so as to reduce loss, conduct the doping function and raise magnetic properties of the product. By the adoption of the method, microstructure of MnZn ferrite is improved; density and magnetic properties of MnZn ferrite are raised; density of a sintered body reaches 5.03 g/cm<3>; saturated magnetic induction density Ms, remanent magnetization Mr and coercive force Hc are respectively 102.8 emu/g, 6.3 emu/g and 20.5 Oe; and saturation magnetic flux density Bs reaches 416 mT. |
