The purpose of the silicon
High purity monocrystalline silicon is an important semiconductor material. In monocrystalline silicon, trace elements of Group IIIA are added to form P-type silicon semiconductor. The combination of n-type and P-type semiconductors, combined with trace amounts of group VA elements, can make solar cells that convert radiant energy into electricity. It is a promising material in the development of energy.
2) Metallic ceramics, important materials for space navigation. Ceramic and metal are mixed and sintered to make cermet composite material, which can withstand high temperature, high toughness, and can be cut, which not only inherits the advantages of metal and ceramic, but also makes up for their congenital defects. The first space shuttle, the Columbia, was able to withstand the heat of friction as it sped through the dense atmosphere thanks to its 31,000 silicon tiles
3) Optical fiber communication, the latest modern means of communication. Instead of bulky cables, the laser passes through the glass fibre's path, which is made of highly transparent glass pulled out of pure silica, with countless times of total reflection. Optical fiber communication capacity is high, as thin as a hair of glass fiber, can transmit 256 channels of telephone at the same time, it is not subject to electrical and magnetic interference, not afraid of eavesdropping, with a high degree of confidentiality. Optical fiber communication will revolutionize human life in the 21st century
4) Silicon organic compounds with excellent performance. For example, silicone plastic is an excellent waterproof coating material. Spraying silicone on the subway walls can solve the problem of water seepage once and for all. On the appearance of antiquities, sculptures, coated with a thin layer of silicone plastic, can prevent moss breeding, resist the wind and rain and weathering. The monument to the People's Heroes in Tian 'anmen Square is made of silicone and plastic, so it is always white and fresh.
