Silicon Metal 441 With Good Quality

Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used in industry as an additive of non-iron-based alloys.  Its main component is silicon, the content of silicon element is about 98% (metallic silicon also contains 99.99% silicon), and the rest impurities are mainly iron, aluminum and calcium. We usually classify metallic silicon according to the contents of iron, aluminum and calcium. According to the contents of iron, aluminum and calcium in silicon metal, silicon metal can be divided into different grades, such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501 and 1101. Silicon metal has semiconductor characteristics. In this information age, silicon has become an indispensable material. In industry, there are not many kinds of semiconductor materials, and silicon accounts for about 90% of the total output of semiconductor materials.

Silicon metal is widely used in electronic industry, mainly for producing silicone, preparing high-purity semiconductor materials and preparing special-purpose alloys. For example, high-purity metallic silicon is the main raw material for producing optical fibers; Modern large-scale integrated circuits used to manufacture high-purity semiconductors are almost all made of high-purity metallic silicon. Silicon is the raw material of ultra-pure silicon in electronic industry. Electronic devices made of ultra-pure semiconductor monocrystalline silicon have the advantages of small volume, light weight, good reliability and long life.

In addition, silicon carbide can be used as abrasive, and quartz tube made of high-purity silicon oxide is an important material for high-purity metal smelting and lighting lamps. People call metallic silicon "the paper of the 1980s". This is because paper can only record information, while silicon can not only record information, but also process information to obtain new information.
