Abstract

The invention discloses a nickel-zinc ferrite material, and a preparation method and a use thereof. The nickel-zinc ferrite material comprises a main component and an additive, and the main componentcomprises Fe2O3, ZnO, NiO, CuO and MnO; and the additive comprises a group IVA oxide, a group IIA oxide, a group VIB oxide, a group IIIB oxide, a group VA oxide and a group IVB oxide. Formula development and trace element modification in the invention overcome the contradiction that improvement of the strength of a magnetic core reduces the high temperature shock resistance or improvement of the thermal shock resistance lowers the strength of the magnetic core, and the high-performance soft ferrite material with a high magnetic permeability, a high Bs value, a high strength and a high thermalshock resistance and for SMD power inductors is developed.

Description

technical field

[0001] The invention belongs to the technical field of soft magnetic ferrite, and in particular relates to a nickel-zinc ferrite material, a preparation method and application thereof. Background technique

[0002] Soft magnetic materials are mainly nickel-zinc and nickel-zinc ferrite, which are important electronic functional materials. Due to the characteristics of high magnetic permeability, high resistivity, and high frequency of use, nickel-zinc ferrite is widely used in computers, communications, and consumer electronics.

[0003] Nowadays, electronic products are developing in the direction of flat, thin and surface mount, and the size of soft magnetic components is getting smaller and smaller. At the same time, the manufacturing process of SMD power inductors has adopted automatic assembly line production, especially the spot welding process, which has a great impact on the strength of the magnetic core and thermal shock resistance. Performance requi...
