Abstract
The invention discloses a low-loss ferrite material with low content of aFMnZn and relates to the field of metallic functional materials for electronic assemblies. The low-loss ferrite material with the low content of aFMnZn comprises 53+/-1 molar percent of ferric oxide, 34+/-1 molar percent of manganese oxide, 12+/-1 molar percent of zinc oxide, 0.10 to 0.20 weight percent of titanium dioxide, 0.10 to 0.20 weight percent of cobalt oxide, 0.05 to 0.10 weight percent of calcium carbonate, 0.05 to 0.10 weight percent of silica, and 0.05 to 0.10 weight percent of vanadium pentoxide. The preparation method comprises the following steps of: designing a formula, weighing, mixing materials, presintering, grinding twice, pelleting, forming, sintering and detecting. The problem of material localization can be solved, cost can be reduced, the performance index of the conventional material can be improved, and loss and temperature coefficients can be reduced.
Description
Technical field:
The present invention relates to electronic package and use the Metallic Functional Materials field, be specifically related to low-loss soft magnetism aFMnZn Ferrite Material.
Background technology:
Ferrite market is along with high-gradient magnetism spare increases and steady growth with magneticsubstance, though ferrite magnetic material has many good qualities with respect to metallicl magnetic material, but it is the alternative metals magneticsubstance fully, it is compared with various high-quality ferrimags also weak point, wherein the most outstanding is that ferritic saturation magnetization is lower, usually the 1/3-1/5 that has only pure iron, this just explanation, because the magnetic energy of storing in the ferrite unit volume is lower, has limited its application in requiring the low frequency of higher magnetic energy density, forceful electric power and high-power field.Nowadays in high-power electric equipment such as the generating of power industry, electronic and transmitting transformer, metallicl magnetic material still can keep its advantage, and ferrite then is difficult to meet the demands.
In addition, along with electronic industry develops device high frequencyization, miniaturization, slimming, integrated direction, also require ferrite to have higher electromagnetic performance.But present system still can not be satisfactory, and the problem of existence mainly comprises: mainly be lot of experiment results is summarized the experience, lack effective theoretical direction in the selection of system and the aspects such as raising of performance 1.The performance of material and the internal relation of electronic structure, chemical bond performance and crystalline structure are not still had systematic study, cause the important basic problem of some microstructure aspects well not to be familiar with; 2, ferrite magnetic material adopts conventional high-temperature solid phase reaction method preparation more at present, not only sintering time is long, be difficult to obtain uniform microstructure, and component is volatile, make product depart from the composition and the formation heterogeneous structure of expection, thereby cause the deterioration and the unstable of material property.
Through looking into domestic and international patent, document and correlation technique data, all do not find relevant material and data.In fact existing this series products of Japan is sold in the continent, and domestic enterprise is by intermediary company's this series products of high price import, and this material is TDK-H6F; The domestic data of literatures that do not inquire as yet at present.
According to senior temperature sensor user profile, there are the research and development of enterprise of a few family in East China, northwest, southwest etc. and produce senior temperature sensor, the magnetic core that they use all is a magnetic core of buying the TDK-H6F material produce by trading company, homemade magnetic core is also arranged, but technical target of the product is not as TDK-H6F, and the technology stability of production and product performance repeatability are relatively poor.
Summary of the invention:
The purpose of this invention is to provide the low aFMnZn Ferrite Material of low-loss, it can solve the production domesticization of this material, reduces cost, and improves the performance index of current material, reduces the wastage, and reduces temperature factor, can reach the TDK-H6F state of the art, tan δ/μ i and a
FIndex is better than the TDK-H6F state of the art, can replace Japanese TDK-H6F material.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it recipe ratio be: ferric oxide-Fe
