Products Description
Crystalline silicon is steel gray, amorphous silicon is black, density 2.4g/cm3, melting point 1420℃, boiling point 2355℃, crystalline silicon is an atomic crystal, hard and shiny, with semiconductor properties. The chemical properties of silicon are relatively active, at high temperatures can be combined with oxygen and other elements, insoluble in water, nitric acid and hydrochloric acid, soluble in hydrofluoric acid and lye, used to make alloys such as ferrosilicon, silicon steel, monocrystalline silicon is an important semiconductor material, used to manufacture high-power transistors, rectifier, solar cells and so on. Silicon is widely distributed in nature, about 27.6% of the Earth's crust, mainly in the form of silica and silicate crystalline silicon is dark blue, very brittle, is a typical semiconductor. The chemical properties are very stable. At room temperature, it is difficult to react with other substances except hydrogen fluoride.
1.High purity monocrystalline silicon is an important semiconductor material. P-type silicon semiconductor is formed by adding a trace of Group IIIA element into monocrystal silicon. A small amount of Group VA elements is added to form N-type and P-type semiconductors, which together can be made into solar cells that convert radiant energy into electricity. It is a promising material for the development of energy sources.
2.Metal ceramics, important materials for space navigation. Ceramic and metal are mixed and sintered to make cermet composite material, which is resistant to high temperature, rich in toughness and can be cut, inheriting the respective advantages of metal and ceramic and making up for the birth defects of both. The first space shuttle, Columbia, was able to withstand the heat generated by friction as it sped through the dense atmosphere thanks to its 31,000 silicon shingles.
3.Optical fiber communication, the latest modern means of communication. Using pure silica to draw a high transparency of glass fiber, laser in the path of glass fiber, countless times of total reflection forward transmission, instead of heavy cables. Optical fiber communication capacity is high, a hair so fine glass fiber, can transmit 256 phones at the same time, it is not subject to electrical, magnetic interference, not afraid of eavesdropping, with a high degree of confidentiality. Optical fiber communication will revolutionize human life in the 21st century.
4.Excellent performance of silicone organic compounds. For example, silicone plastics are excellent waterproof coating materials. Spraying silicone on the four walls of the underground railway can solve the problem of water seepage once and for all. On the appearance of ancient relics and sculptures, a thin layer of silicone plastic can prevent moss from breeding and resist wind, rain and weathering. The monument to the People's Heroes on Tiananmen Square is made of silicone plastic, so it is always white and fresh.
