For making the object, technical solutions and advantages of the present invention clearly understand, below by the specific embodiment shown in accompanying drawing, the present invention is described.But should be appreciated that, these describe just exemplary, and do not really want to limit the scope of the invention.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present invention.
As shown in Figure 2, this embodiment is by the following technical solutions: its Making programme is:
(1), powder:
(1.1), powder formulation: except the purity of raw material, outside the detection confirmation of granularity and particle shape, on the ratio formula of material, set up raw and auxiliary material database, determine raw-material purity, granularity, specific surface area, homogeneity, the fill characteristic of powder, impurity content and kind, the indexs such as moisture content, set up starting material Check and Inspection system, establish examinaing method and standard, adjusted by the mode such as thermal treatment and vibratory milling and control raw and auxiliary material containing assorted and granularity and distribution thereof, control ratio surface-area and raw material solid phase reactive behavior, thus for the variant production requirement that different client proposes, make high μ Q material.
In current raw material ratio database, from soft magnetic ferrite crystalline structure, grain growing, compactness and the impact of macroscopical magnetic properties that finally shows, the existing batching of part and the following subordinate list of formulation ratio:
| Composition table | Fe2O3 | MnCO3 | ZnO | TiO2 | CaCO3 | H2SiO3 | Ho2O3 |
| Example one | 51.00 | 38.00 | 10.00 | 0.60 | 0.32 | 0.05 | 0.03 |
| Example two | 51.50 | 37.50 | 9.90 | 0.70 | 0.32 | 0.04 | 0.04 |
| Example three | 52.00 | 37.00 | 9.80 | 0.80 | 0.32 | 0.03 | 0.05 |

| Example five | 53.00 | 36.00 | 9.60 | 1.00 | 0.32 | 0.01 | 0.07 |
(1.2), powder water content technology: moisture content is one of critical control point of product, and moisture is overweight, can cause product adhesion in compression moulding process, cause density to reduce, cause difficulty to shaping; Hypohydration, easily cause product ftracture and internal fissure, reduce product performance, its moisture needs the content remaining on 0.8 ‰, therefore control moisture and Homogeneous Aqueous amount most important.
Adopt advanced equipment namely to be carried out control and the research of water content by high-pressure atomization principle, reach the zone of reasonableness of water content, promote the high-performance of material, reach the object obtaining excellent high μ Q material.
(2), mist projection granulating: adopt spray drying granulation technique, granular size evenly, consistence is better, and powder particles size can control within the scope of 3-5 μm; Particle good sphericity, even particle size distribution, mobility of particle is good, is conducive to the densification of product.
(3), pre-burning: adopt 800 DEG C of-820 DEG C of calcined temperatures, soaking time 4-5 hour, improve density, make solid state reaction complete, be conducive to the electromagnetic performance improving sample.
(4), mix grinding granulation: after mist projection granulating carries out pre-burning, try again granulation process, both ensure that powder mixed effect, again reduced the energy.
(5), shaping: particular manufacturing craft compression moulding, pressure when controlling supplied materials water content, compression moulding and product density and substance, meet compact density at 3.0-3.5g/cm3, consistence is good, for next step sintering is laid a solid foundation.
(6), sinter: adopt at present state-of-the-art bell-jar agglomerating plant in the world, improve sintering atmosphere and technique, optimize sintering temperature, explore the impact of sintering condition on grain-size, homogeneity, phase structure phase composite, sintering temperature, time and Ferrite Material electromagnetic performance relation.
Sinter the whole cycle at 20-22 hour.Sintering temperature controls within the scope of 1100-1150 DEG C, and the time ensures 3 hours, improves homogeneity of product and stability with this, ensures product high comprehensive performance.Summary makes the sintering time of product shorten 20%, reduces production cost.
(7), detect: test product being carried out to characteristic, inductance value ,-25 DEG C-+125 DEG C positive and negative temperature shock magnetic properties.
(8), vacuum coat: adopt advanced vacuum vapor deposition paint-on technique to develop, the proof voltage of product is punctured can reach >=more than 1800V, the highlyest can reach more than 3000V.Coat thickness is strict controlled in 0.002mm, avoided the thin material that causes to lose de-protected insulation layer effect, blocked uply also cause the insulation layer in winding process to break, naked effect, or affect the dimensional problem that client uses.
This embodiment brings up to about 1,000,000 by making μ Q product by about 650,000 on current industry, market, thus make MnZn soft magnetic ferrite material performance more superior, this high μ Q-MnZn material can better meet in every technology such as high-end communication, satellite-navigation, electromagnetism interference, electromagnetic compatibility technology, missile guidance, enemy and we's identification, electronic countermeasure, be satisfied with all requirements of client, thus reduce costs.
This embodiment break soft magnetic ferrite high stable, low-loss height μ Q material μ Q product about 600,000 situation, μ Q product is made to bring up to about 1,000,000, thus make material property more superior, better meet all requirements in client, broader applications are in every profession and trade, requirement especially to soft magnetic ferrite in high-end communication or aerospace, defense technology, reduce this type of high performance material situation of dependence on import, impel industry development and the spare part such as network filter and transformer cost is declined.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
