Abstract

A high magnetic conductivity core material is composed of a main material and microchemicals among which, the main material is counted in mol%: Fe2O3 52-54, Mn3O4 26-28 and ZnO for rest added by microchemicals V2O5, BizO3, CaCo3. The said microchemicals: V2O5, 0.01-0.02, SiO2 0.02-0.035, CaCO3 0.0125-0.025 in weight of main material with the advantage of obviously increased magnetic conductivity, ui is greater than or equal to 7.7KmH/m when F=10KHz in actual test.

Description

High magnetoconductivity 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 magnetic permeability of general magnetic ferrite magnetic core material is lower, its magnetic permeability (during F=10kHz) μ i≤5kmH/m, 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 magnetic permeability, by the improvement to the composition of material, thereby realize the raising of its performance.
A kind of high magnetic permeability core material of the present invention is made up of major ingredient and minor compound, and wherein major ingredient is by mol%: Fe 2O 352-54, Mn 3O 426-28, all the other are ZnO; And in major ingredient, add minor compound V 2O 5, Bi 2O 3, CaCo 3
Described minor compound is respectively: V by major ingredient weight % 2O 50.01-0.02, SiO 20.02-0.035, CaCo 30.0125-0.025.
The invention has the advantages that prescription after improving, the magnetic conductivity of Ferrite Material obviously improves, the magnetic conductivity μ i 〉=7.7kmH/m when surveying its F=10kHz.
