Abstract

The invention discloses a ferrite core material with high magnetic energy product. The ferrite core material comprises a main ingredient and additives, wherein the main ingredient comprises the following components in molar ratio: 64-68.1mol of Fe2O3, 14.6-20mol of manganese oxide, 14.3-16.5mol of zinc oxide, 0.2-0.5mol of graphite, 0.2-0.3mol of tungsten carbide and 0.01-0.02mol of boron oxide coated carbonyl iron powder; the additives, measured by accounting for the weight ratio of the ferrite core material, comprises 500-600ppm of copper oxide, 400-500ppm of nickel oxide and 20-50ppm of lithium nitride. The boron oxide coated carbonyl iron powder is added into the ferrite core material to achieve high magnetic flux at high frequency and ultra high frequency and further improve the overall performance of a finished product; and the core material disclosed by the invention has the characteristics of high magnetic energy product, stable magnetism, strong mechanical property and the like.

Description

technical field [0001] The invention mainly relates to the field of manufacture of oxide magnetic materials, in particular to a high energy product ferrite core material. Background technique [0002] With the development of communication technology and digitalization of electronic products, new requirements are put forward for soft ferrite and components. High-performance and high-permeability magnetic cores are widely used in various basic materials for telecommunications and information, such as common-mode filters, Saturated inductors, current transformers, leakage protectors, insulation transformers, signal and pulse transformers and other fields have been widely used. Now the electronic communication industry needs ferrite cores with low core loss and high magnetic permeability to meet the miniaturization and high efficiency requirements of electrical equipment. The existing magnetic cores are difficult to meet the above requirements; [0003] Carbonyl iron powder...
