Metal Silicon With A High Degree Of Confidentiality

Henan Xinxin Silicon Alloy Co.,Ltd | Updated: Sep 30, 2017

Silicon is indispensable in industrial production, there are many kinds of silicon, with different metals have different roles, the following we come to you briefly about the silicon family of two most common - silicon and silicon carbide The

The use of Metal Silicon  is widely used and is widely used in our daily life as well as in industry

Metal Silicon  is made of quartz and coke in the electric furnace smelting into the product, the main component of silicon content of about 98% (in recent years, containing 99.99% of Si is also famous in the metal silicon), the remaining impurities for the iron, aluminum , Calcium and so on.

One of the uses of Metal Silicon : cermet, an important material for aerospace navigation. The metal silicon and metal mixed sintering, made of cermet composite material, it is high temperature, toughness, can be cut, both inherited the advantages of metal and ceramics, but also make up for both the inherent defects. Can be applied to the manufacture of military weapons The first space shuttle "Columbia" can withstand high-speed wear through the dense atmosphere of the high temperature caused by friction, thanks to its thirty thousand thousand pieces of silicon tile into the shell.

The use of metal silicon two: excellent performance of silicon organic compounds. For example, metal silicon silicone plastic is an excellent waterproof coating material. Spraying silicone on the walls of the underground railway can solve the problem of water seepage once and for all. In the ancient artifacts, sculpture appearance, coated with a thin layer of silicone plastic, can prevent the moss breeding, against wind and rain and weathering. Tiananmen Square, the People's Heroes Monument, is treated by silicone plastic surface, so always white, fresh.

The use of metal silicon three: high purity metal silicon is an important semiconductor material. In the monocrystalline silicon doped with a small amount of Group IIIA elements to form p-type silicon semiconductors; incorporation of trace elements of Group VA, the formation of n-type and p-type semiconductors together can be made of solar cells, the radiation energy Into electricity. In the development of energy is a very promising material.

The use of Metal Silicon  four: optical fiber communication, the latest modern means of communication. With the silicon metal to draw a high degree of transparency of the glass fiber, the laser in the glass fiber access, numerous times the total reflection forward transmission, instead of the bulky cable. Fiber optic communication capacity is high, a hair so fine glass fiber, you can also transmit 256 phone, it is not power, magnetic interference, not afraid of eavesdropping, with a high degree of confidentiality. Fiber communication will make the 21st century human life revolution.

1, metal silicon in the crust is extremely rich in resources, second only to oxygen, accounting for a quarter of the total crust is also strong, in the form of silica or silicate. A melting point of 1420 ° C and a density of 2.34 g / cm. Hard and brittle. At room temperature insoluble in acid, soluble in alkali.

2, metal silicon has two kinds of allotropes: a dark brown amorphous powder, the nature of lively, can burn in the air; the other for the stability of the crystal (crystalline silicon). General silica and quartz for glass and other building materials, high quality quartz for the production of alloys, metals and single crystals.
