| Soft ferrite materials in electronic information | | | | important is the soft ferrite production of |
| and home appliance industries an important | | | | electronic components as its main raw materials |
| functional material. Into the 21st century, as | | | | has brought endless demand. With soft ferrite as |
| technology progresses, the soft ferrite materials, | | | | the main raw materials, soft ferrite components, |
| the demand will continue to increase, performance | | | | as a basis for functional product, have infiltrated all |
| requirements will be continuously improved. Soft | | | | areas of human production and life, in terms of |
| ferrite industry in China developed very quickly, | | | | resources or from the application point of view, |
| the market prospect is broad. | | | | soft ferrite cores prospects for the development |
| Magnetic materials in modern industry and science | | | | of components are very broad, and its demand |
| and technology play a pivotal role in mechanical, | | | | will certainly be increasing. In recent years, |
| electronic, information and other product | | | | computers, mobile communication, optical fiber |
| performance leap to make a significant | | | | communications, EMC, DVD, digital TV and new |
| contribution is to support and promote social | | | | lighting, etc. The rapid development of applications |
| development, crucial documents. Industrial | | | | for soft ferrite opened up a bigger market share. |
| production and practical application of the most | | | | In this market, a fast-growing soft ferrite |
| widely used magnetic materials can be divided into | | | | products mainly include the following categories: |
| cast magnets, soft ferrite, hard ferrite and | | | | power ferrite, accounting for about 50% of the |
| rare-earth permanent magnet four groups. Soft | | | | total soft ferrite; high permeability ferrite, about |
| Ferrite is the largest and most widely used | | | | the total 25%; broadband RF and electronic |
| varieties of a magnetic material, electronic | | | | ballasts and lighting transformer ferrite, accounting |
| information and home appliance industry and other | | | | for about 10% of the total; anti-electromagnetic |
| important basic functional material. At present, the | | | | interference (EMI) ferrite components, accounting |
| world's output of magnetic material is about 1.277 | | | | for 5% of total output. |
| million t, of which the output of soft ferrite is | | | | Ferrite production investment is large, wide area, |
| about 386,000 t, accounting for about 30% of | | | | is a high energy-consuming and labor-intensive |
| total output. China's output of magnetic material is | | | | industries. China has cheap labor, abundant raw |
| about 637,000 t, of which the output of soft | | | | material resources and energy, also has a large |
| ferrite is about 205,000 t, accounting for about | | | | number of manufacturers of electronic |
| 32% of total output. | | | | transformers and inductors, as well as the world's |
| Applications | | | | largest color TV, monitors, computers and |
| Ferrite can be classified by application of high | | | | peripherals industry. Therefore, the main producing |
| permeability ferrite, power ferrite ferrite and | | | | ferrite has gradually shifted from Japan, the |
| anti-electromagnetic interference. High permeability | | | | United States, Western Europe and other |
| ferrite mainly refers to the initial magnetic | | | | countries move to China is conducive to |

| permeability ferrite cores prepared significantly | | | | According to the relevant departments and |
| reduced in size to meet the component to the | | | | experts predict that in the next 5-10 years, the |
| smaller and lighter development needs in the | | | | world's average annual growth rate of soft ferrite |
| electronics industry and electronic technology, | | | | market will remain at 6% ~ 10%, while China will |
| widely used, they can do communications | | | | be 15% ~ 20% of the average annual growth |
| equipment, measurement and control instruments, | | | | rate the rate of development. It can be predicted |
| household electrical appliances in the wideband | | | | that by 2010, China soft ferrite market demand |
| transformers, transformers and micro-miniature | | | | will be higher than 300,000 t, which will give |
| low-frequency inductance elements. Power ferrite | | | | domestic enterprises to provide a huge ferrite |

| (several thousand Gauss) conditions, it can | | | | Japan's TDK products, PC40 and H5C2 and above |
| maintain a low-power, and its power consumption | | | | series), the market demand is also increasing |
| decreases as the core of the temperature at 80 | | | | every year. High-performance Ferrite Soft Ferrite |
| ℃ reached its lowest point around, forming a | | | | account the ratio of total demand in 2000 |
| virtuous cycle of Mn-Zn ferrite. Power ferrite is | | | | increased 10% or less in 2005, more than 30% |
| mainly used for switching power supply | | | | (PC40 and over 20000 t, H5C2 and over 10000 |
| transformers and flyback transformers and other | | | | t). Some foreign components, machine supporting |
