Abstract

A high frequency low loss soft magnet ferrite core material is composed of master and auxiliary materials, in which, the master is counted in mol%: Fe2O3 51-53, Mn3O4 34-36 and ZnO for rest added by microchemicals of V2O5, SiO2 and CaCO3 counted in weight % of the master material: V2O3 0.02-0.03, SiO2 0.00125-0.0025, CaCO3 0.025-0.05 with the advantage of obviously reduced loss of ferrite material under high frequency and Pcvis less than or equal or 400kw/m2 at 100KHz in actual test.

Description

High frequency low loss soft magnetic ferrite magnetic core material
Affiliated technical field
The present invention relates to a kind of magnetic ferrite magnetic core material.
Background technology
Magnetic ferrite magnetic core material can be widely used in the every field such as Aero-Space, automatically control, electric power, automobile, medicine equipment, household electrical appliance, and is further used in converter technique.In the prior art, the high-frequency loss of general magnetic ferrite magnetic core material is higher, and the power loss Pcv during its high frequency (100kHz) is about 600kW/m 2, so its application is affected.
Summary of the invention
The objective of the invention is to propose a kind of magnetic ferrite magnetic core material of high-frequency low-consumption, by the improvement to the composition of material, thereby realize the raising of its performance.
A kind of high frequency low loss soft magnetic ferrite magnetic core material of the present invention is made up of major ingredient and minor compound, and wherein major ingredient is by mol%: Fe 2O 351-53, Mn 3O 434-36, all the other are ZnO; And in major ingredient, add minor compound V 2O 5, SiO 2, CaCo 3
Described minor compound is respectively: V by major ingredient weight % 2O 50.02-0.03, SiO 20.00125-0.0025, CaCo 30.025-0.05.
The invention has the advantages that prescription after improving, the loss of Ferrite Material under high frequency obviously reduces, the power attenuation Pcv when surveying its high frequency (100kHz)≤400kW/m 2
