In 2010, the output value of Taiwan's electronic materials industry grew by 44% compared with 2009, reaching NT$244.7 billion. Among them, the growth rate of energy materials such as silicon epitaxial wafers and polysilicon materials for solar cells was up to 78%. In 2020, the output value of Taiwan's electronic materials industry is expected to exceed NT$600 billion. The material industry, especially the optoelectronics industry, is currently in the form of green environmental protection and resource shortage, and its development contributes to the development and transformation of the overall industry. The Taiwan Ministry of Economics evaluates the marketability, job creation, and the link of green growth. Standards, selected 24 of the 2020 core industries, including advanced electronic materials. In mainland China, new materials including "electronic information materials" and "new energy materials" have been listed as one of the seven "strategic emerging industries" to focus on development. Taiwan's Ministry of Economic Affairs said that the development of electric vehicles under the trend of green environmental protection, the rise of touch panels to promote a new interactive mode, the rise of emerging LED lighting and OLED displays, including positive and negative materials for lithium batteries, LED heat sink materials, OLED lighting and packaging Materials and materials have potential for development. At the same time, in response to the high metal prices and the export of China's controlled rare earth minerals, Taiwan's medium and long-term development of alternative technologies for electronic technology and rare metals can be developed.
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
