Abstract
The invention provides a nickel-zinc ferrite material for a magnetic core. The nickel-zinc ferrite material is prepared from the following components in percentage by mass: 42-50% of ferric oxide, 42-48% of nickel oxide, 2-16% of zinc oxide and 0.5% or less of impurities, wherein the content of each impurity element component is less than 0.05%, and the nickel-zinc ferrite material for the magnetic core prepared by the method has good initial permeability and coercive force and can meet special requirements of the transformer industry.
Description
technical field [0001] The invention relates to the field of magnetic core manufacturing, in particular to a nickel-zinc ferrite material for a magnetic core. Background technique [0002] The magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. It can increase the magnetic flux density of the magnetic circuit of the electromagnetic coil and reduce the copper loss to increase the electromagnetic induction intensity and improve the voltage conversion efficiency when used in the circuit. The performance of the magnetic core has a great impact on the transformer, so improving the performance of the magnetic core has always been the focus of research in the industry. [0003] In the prior art, the manganese zinc ferrite material cannot meet the special requirements of the transformer during use. Contents of the invention [0004] The technical problem to be solved by the present invention is that in the prior art, the manganese-zinc ferrit...
