Abstract

The invention relates to a high-frequency ultralow-consumption manganese-zinc soft magnetic ferrite material and a preparation method thereof. The high-frequency ultralow-consumption manganese-zinc soft magnetic ferrite material consists of the following components in parts by mass: 140-146 parts of Fe2O3, 39-48 parts of Mn3O4, 8-15 parts of ZnO as main components. Trace amounts of CaCO3, CoO andCr2O3 are added for a first time, trace amounts of Y2O3, Sm2O3, SiO2 and V2O5 are added for a second time, and by using a solid-phase method, a high-frequency ultralow-consumption magnetic core material is prepared through material blending, sand milling, doping, pelletizing, molding and atmosphere sintering. Under conditions of 100 DEG C, 1MHz and 30mT, the testing power consumption of the material is less than 90kW / m<3>. The material is small in energy consumption, green and environment-friendly and good in comprehensive property, and can be applied to fields such as laser emitter power supplies, vehicle-mounted electron number submodules and aerospace large power supplies.

Description

technical field [0001] The invention relates to a soft ferrite material, in particular to a high-frequency ultra-low loss manganese-zinc soft ferrite material and a preparation method thereof. Background technique [0002] Soft ferrite is the basic material of IT industry and electronics industry. The industrially produced soft magnetic ferrite materials are currently mainly divided into manganese zinc ferrite, nickel zinc ferrite and copper zinc ferrite, among which manganese zinc ferrite has the largest output. With the development of electronic science and information technology, manganese zinc soft magnetic ferrite has become an extremely important magnetic material for electronic components, because of its high initial permeability, high saturation magnetic flux density, low coercive With excellent characteristics such as high strength and low power loss, manganese zinc soft ferrite is widely used in electronic devices such as communication technology, power supply equ...
