Power-type low-temperature sintered NiZn ferrite material and preparation method thereof
The invention relates to the field of ferrite materials and discloses a power-type low-temperature sintered NiZn ferrite material and a preparation method thereof. The power-type low-temperature sintered NiZn ferrite material comprises a main component and an auxiliary component. The main component is prepared from powdery oxides of NiO, ZnO and Fe2O3 and the auxiliary component comprises nanoscale impurities. The main component is added with Co frozen domain wall. In the main component, Co ion content is less than or equal to 0.030 moles, Zn ion content is less than or equal to 0.800 moles, and Fe ion content is less than or equal to 1.950 moles. The power-type low-temperature sintered NiZn ferrite material is suitable for being used in a LTCF sheet-type power device, has technical indexes of magnetic permeability less than or equal to 700, power consumption Pv less than or equal to 300kW/m<3> (20 DEG C, 1MHz and 30mT), saturation magnetic flux density Bs greater than 320mT (1.2KA/m) and a sintering temperature of about 900 DEG C.
