High-performance nanometer LiZn ferrite magnetic core material
The invention discloses a high-performance nanometer LiZn ferrite magnetic core material. The high-performance nanometer LiZn ferrite magnetic core material is prepared by mixing Fe(NO3)3.9H2O, Zn(NO3)2.6H2O, LiNO3, and water to prepare a matrix solution; mixing C6H8O7.H2O with water to prepare a complex agent solution; mixing the obtained substrate solution and the obtained complex agent solution; adding ammonium hydroxide into the mixed solution till the pH value reaches the range of 6.8-7.2, and mixing the obtained mixed solution to obtain sol; drying the sol to obtain xerogel and performing self propagating combustion to obtain ferrite nano-powder; moulding the obtained ferrite nano-powder; and elevating the temperature to 920-980 DEG C from the room temperature at a heating rate of 3-3.6 DEG C/min, and performing sintering in the presence of oxygen for 110-120 min to obtain the ferrite material, wherein the heating rate is increased at first and is decreased later with the temperature increases during the temperature elevating process, and the temperature, at which the heating rate changes, is in a range of 700-720 DEG C.
