Description
Technical field
The invention belongs to soft magnetic ferrite fields, and in particular to a kind of high frequency power soft magnetic ferrite and its system
Preparation Method.
Background technology
With the development of electronics science and information technology, Mn-Zn soft magnetic ferrite increasingly becomes a kind of extremely important electricity
Sub- component magnetic material, since it is with high initial permeability, high saturation magnetic flux density, low-coercivity, low-power consumption etc.
Excellent characteristic, Mn-Zn soft magnetic ferrite are widely used in the electronic devices such as the communication technology, power-supply device, computer product.
In recent years, since electronic component constantly develops to high density, miniaturization, chip type, integrated direction, MnZn is correspondingly required
The various characteristics of soft magnetic ferrite will also improve.
Powerful Mn-Zn soft magnetic ferrite is mainly used for magnetic core of transformer, works in high-power state, therefore
The power for improving Mn-Zn soft magnetic ferrite is of great significance to the development in the even entire electronic component field of transformer.
The content of the invention
In order to solve the problems, such as that prior art exists, the power of manganese-zinc ferrite is improved, improves manganese-zinc ferrite material
The stability of material, adapts to performance requirement of the communications industry to soft magnetic ferrite, and the present invention proposes a kind of high frequency power soft magnet oxygen
Body material, mainly including following component：
Major ingredient
Fe2O3：52~56mol%、MnO：34~38 mol%、ZnO：10~15 mol%.
Auxiliary material
Bi2O3：100~400ppm、TiO2：50~150ppm、Co2O3:150~200ppm、SiO2：10~50ppm、CaO：10~
50ppm、SnO2：10~30ppm、Cr2O3：10~30ppm.
The present invention also provides a kind of above-mentioned preparation methods of high frequency power soft magnetic ferrite, include the following steps：
（1）Dispensing, by each component according to said ratio dispensing；
（2）The raw material prepared is put into adverse current batch mixer and mixes by batch mixing and slurrying, 1 ~ 2h of mixing time；
（3）Pre-burning carries out pre-burning, 700 ~ 1000 DEG C of calcined temperature, burn-in time in rotary kiln：3~5h；
（4）Mixture after pre-burning is put into 20 ~ 40min of ball mill coarse powder essence by coarse crushing；
（5）Mist projection granulating, using spray drying granulation, the temperature for being passed through hot-air is 260 ~ 280 DEG C；
（6）It is finely divided, it is sanded using circulation type sand mill, 3 ~ 6h of time is sanded, while adds in above-mentioned raw materials gross mass
0.2 ~ 0.5% butyl stearate is as lubricant；
（7）Secondary mist projection granulating：Using spray drying granulation, the temperature for being passed through hot-air is 300 ~ 350 DEG C；
（8）Shaping, by step（7）The pellet compression moulding of acquisition；
（9）Sintering carries out atmosphere sintering using nitrogen list push plate sintering furnace, and sintering temperature is 1300 ~ 1500 DEG C.
Further, the step（9）In keep the temperature 1h at 1100 DEG C.
Preferably, the Fe2O3For 53.1 mol%.
Preferably, the MnO is 36.2 mol%.
Preferably, the ZnO is 11 mol%.
The present invention cardinal principle be：CaO and SiO is added in major ingredient2, the two reaction generation CaSiO3The shape in crystal boundary
Into resistive formation, the loss factor of soft magnetic ferrite can be reduced.However excessively high CaO can increase soft magnetic ferrite
Disaccommodation, excessively high SiO2It is easy to cause that crystal grain is discontinuous to grow up in the sintering of soft magnetic ferrite, it is magnetic to reduce its.
TiO2Can and SiO2, Mn generate another phase in crystal boundary, form grain boundary layer, advantageously reduce soft magnetic ferrite
Power attenuation.In addition Ti ionic portions substitution Fe ions, can be by body sintering temperature, without promoting grain growth, convenient for obtaining
Smaller even grained and low-porosity are obtained, so as to reduce magnetic hystersis loss.
Add Co2O3The temperature characterisitic of material can be controlled, reduces magnetic hystersis loss.
