Soft magnetic ferrite industry development and the future of our country

Soft magnetic ferrite materials is one of the important function of electronic information and household appliances industry material. After entering the 21st century, with the constant progress of science and technology, the demand of soft magnetic ferrite materials will continue to increase, the performance requirements will also be increased continuously. The development of soft magnetic ferrite industry very quickly in our country, the wide prospect of market.

magnetic material in modern industry and science and technology plays an important role on the properties of mechanical, electronic and information products such as leap made a significant contribution, is a key material support and promote the development of the society. Industrial production and the actual application of the most widely, soft magnetic ferrite magnetic materials mainly divided into casting magnet, permanent magnet ferrite and rare-earth permanent magnet four categories. Varieties of soft magnetic ferrite is a kind of magnetic materials and application of the most widely most, is the important basic functions of electronic information and household appliances industry, etc. At present, the world production of magnetic materials is about 127. 70000 t, the production of soft magnetic ferrite is about 38. 60000 t, accounting for about 30% of the total output. The output of magnetic materials in China is about 63. 70000 t, the production of soft magnetic ferrite is about 20. 50000 t, accounting for about 32% of the total output.

application soft magnetic ferrite by application can be divided into high permeability ferrite, ferrite power ferrite and resistance to electromagnetic interference. High permeability ferrite mainly refers to the initial permeability is greater than 5000 Mn - Zinc ferrite. High permeability ferrite preparation greatly reduce the volume of the magnetic core, meet the needs of the development of components to miniaturization, lightweight, widely used in electronic industry and electronic technology, can do communication equipment, measurement and control instruments, household electrical appliances in the broad band, miniature low frequency transformer and miniature inductance components, etc. Power ferrite mainly refers to in a certain frequency ( A few hundred thousand MHZ) And the magnetic induction ( Thousands of gaussian) Conditions, can maintain a low power consumption, and as the core temperature rise and reduce power loss and demand reached a low point in 80 ℃ or so, a virtuous circle of Mn - Zinc ferrite. Power ferrite is mainly used in switching power transformer and flyback transformer power inductors, is currently the largest output of soft magnetic ferrite. Resistance to electromagnetic interference ferrite mainly refers to the wide band within the scope of the energy of the rf signal transmission and Ni - impedance transformation Zinc ferrite. Use the Ni - in the system Department of zinc ferrite preparation of filter and suppressor device is a very effective and simple, the realization of economic resistance to electromagnetic interference.

and the production of soft magnetic ferrite market market demand

soft magnetic ferrite in the industrial application began in the late 19th century, is accompanied by the rise of power electrical and telecommunications technology, its application scope is extremely broad. Soft magnetic ferrite is not only applied in the field and informatization home appliance, automobile industry and other areas, more major is soft magnetic ferrite as the main raw material of electronic components production has brought a steady stream of demand for it. Soft magnetic ferrite as the main raw materials, ferrite soft magnetic components as the basic function of a product, has penetrated into every field of human production and living, whether from a resource or from the point of view of application, ferrite soft magnetic components development prospects are very broad, its demand will grow. In recent years, computers, mobile communication, optical fiber communication, EMC, DVD, digital TV, and the rapid development of the new illumination lamps and lanterns, etc, for the application of soft magnetic ferrite opened up a bigger market. In this market, rapid development of soft magnetic ferrite products mainly has the following categories: power ferrite, accounts for about 50% of the amount of soft magnetic ferrite; High permeability ferrite, accounts for about 25% of the total. Broadband radio frequency (rf) and electronic ballasts and lighting transformer with soft magnetic ferrite, accounts for about 10% of the total. Resistance to electromagnetic interference, EMI) Ferrite components, accounts for about 5% of the total output.

production of soft magnetic ferrite greater investment, covers an area of broad, is a kind of industrial energy intensive and requires a lot of labor. China has cheap labor, abundant raw material resources and energy, but also have a large number of electronic transformer and inductor manufacturers as well as the world's largest color TV, display, computers and peripherals to manufacturing. So the leading producer of soft magnetic ferrite has gradually by Japan, the United States, Western Europe and other countries to move to China, which is conducive to China's market demand of soft magnetic ferrite. According to the relevant departments and experts predict, 5 - in the future 10 years, the average annual growth rate of soft magnetic ferrite markets around the world will remain at 6% ~ 10%, while in our country will develop an average annual growth rate is about 15% ~ 20%. Predictably, 2010 years later, the market demand will be higher than 300000 t of soft magnetic ferrite, it will provide a soft magnetic ferrite domestic enterprises with huge space for development.

our high performance soft ferrite ( Equivalent to the Japanese TDK product PC40 and H5C2 and above series) Market demand is also increasing year by year. The proportion of high performance soft ferrite soft magnetic ferrite total demand increased from 10% in 2000 to the following to more than 30% of the 2005 ( PC40 and above 20000 t, H5C2 and above 10000 t) 。 Abroad some of the components, machine company, such as MOTOROLA, NOKIA mobile phone company, BELL, LUCHUN, such as communications, computer companies such as IBM, DELL, and SONY, panasonic, Toshiba, samsung, such as a large number of well-known home appliance manufacturing companies to build factories in China, contributed to the market demand for high quality soft magnetic ferrite. In addition, our country has joined the WTO, under the trend of global economic integration, forced soft magnetic ferrite components industry to set both the domestic and foreign markets and to grasp the new consciousness, new ideas. All of this will lead to China's overall level of soft magnetic ferrite industry and increase of production and promote the development of soft magnetic ferrite industry in our country.
