As the ceaseless development of electronic technology, the progress of active parts of an apparatus, electronic product volume and weight decrease greatly, this was driven include electronic transformer inside electron yuan parts of an apparatus develops to light, thin, little direction. The manufacturing technology of electronic transformer is faced with to change tremendously, electronic transformer to high frequency change, little direction of light, volume develops small loss, weight is inevitable trend, the soft magnetism core that regards electronic transformer core as the component will be this changing be the first to be affected component, consequently promotion application has the blame with conductance of feeling of tall saturated magnetism, tall initiative magnetism and high frequency small loss material of alloy of soft china of crystal of brilliant accept rice uses as magnetism core will promote electronic transformer greatly the miniaturization of electronic transformer, satisfy the development need of electronic industry.

Learn the development of technology and fast oil technology as Namike at present, material of all sorts of new-style accept rice if the ceaseless development such as stuff of material of powder of accept rice brilliant, accept rice film and stuff of film of accept rice grain comes out, material of these new-style accept rice, once industrialization, will promote electronic transformer greatly to high frequency, miniaturization, piece type changes directional development.

2. The application of material of alloy of brilliant of rice of blame brilliant accept in electronic transformer

Will tell commonly, electronic transformer basically has the following demand to its core material: (1) tall saturated magnetism feeling; (2) as far as possible small high frequency loss; (3) tall initiative magnetism conductance; (4) high Courier temperature and good temperature stability; (5) environmental stability is good, corresponding force is not sensitive; (6) some utility still ask like pulse transformer tall rectangle compares Br/Bs or low Br. Material of alloy of soft china of crystal of rice of the accept that be not brilliant because its area is large with resistor the element such as rate decides to be inside 50~1000kHz limits (it is normally under hundreds of KHz) can achieve afore-mentioned function to ask, this makes alloy of brilliant of rice of the accept that be not brilliant current in this one frequency paragraph inside development application is very active, already developed various magnetic parts of an apparatus to apply extensively at power industry, electron industry and domain of electric power electron, use as the transformer of power source of voltaic transformer, switch, inversion power source and power source of programmed control switching equipment, reactor, filter and fight EMI parts of an apparatus to wait.

The author thinks in the following respects at present existence extends applied market:

(1) . Replace product of paper-thin silicon steel, grind from Shanghai steel demand knows a market of product of paper-thin silicon steel, paper-thin silicon steel (ply <0.1mm) in 20 centuries 70 time are used at 400Hz above in great quantities all sorts of electron component are like screen of high frequency transformer, reactor, magnetism to wait, demand of this respect market is at present bigger, but need for just satisfying the market hard, use material of alloy of brilliant of rice of the accept that be not brilliant to replace, can improve a product not only function, quality and make miniaturization, and on the price profitable also.
