The use of silicon element

Also with high temperature resistance, electrical insulation resistance, oxidation stability resistance, weather resistance, hard to burn, hate water, corrosion-resistant, non-toxic, odorless and physiological inertia and other outstanding features, widely used in the aerospace, electrical and electronics, construction, transportation, chemical industry, textile, food, light industry, medical industry and so on, wherein the silicone is mainly used in sealing, bonding, lubrication, coating, surface active, demoulding, defoaming, waterproof, moisture-proof, inert fillers and so on. With the continued growth of the number and variety of organic silicon, applications continue to widen, form of unique product system in new chemical materials sector, many varieties which is other chemicals can not replace but essential.

Silicon is a semiconductor material, can be used for producing semiconductor devices and integrated circuits. Also can be used in the form of alloy (such as silicon alloy), used in automotive and machinery parts. Also be together with ceramic materials used in metal ceramics. Can also be used in the manufacture of glass, concrete, brick, refractory, siloxane, silane.

The brick, tile, gravel, cement, glass used in building house, food and water bowl, cups, ware in washroom, they were looking very different, in fact, the main ingredient are silicon compounds. Although people in ancient times had been use silicon compounds clay to make pottery. But until 1823, Swedish chemist was first isolated silicon, flaming the silicon in oxygen to generate silicon dioxide, and determine the silicon is a new element. According to metal powder supplier, it is the main element to constitute minerals and rocks. Silicon in nature have not free state, they were presented in the compounds. The silicon compound is mainly the silicon dioxide (silica), and silicate. For example, granite is composed of quartz, feldspar, mica mixed, quartz is a form of silica, feldspar and mica is silicate. Sand and sandstone is the variants of impure silica, is the product of natural silicate rock weathering. Silicon account for about 27.72% of the total weight of the crust, the content is only second to oxygen.

Silicon is a nonmetallic element, have amorphous silicon powder and crystalline silicon two allotropes, crystalline silicon has metallic luster and some metal characteristics, so that often referred to as prepare metal elements. Silicon is an important semiconductor material, doped with trace impurities in the silicon single crystal can be used to manufacture power transistors, rectifier, the solar cell and the like. Silicon dioxide (silica) is the most common compounds, very widespread in nature, constitute a variety of minerals and rocks. The most important crystalline silica is quartz. Transparent quartz crystal called crystal, black and almost opaque quartz crystal called smoky quartz. Quartz hardness is 7. Quartz glass can through UV, can be used to manufacture mercury vapor UV lamp and optical instruments. There are also have amorphous silicon powder in nature, called diatomaceous earth, commonly used as the adsorbent of glycerol explosives (nitroglycerin), also can be used for insulation, sound insulation material. Common sand is the materials of manufacturing glass, ceramics, cement and refractory. The products of the silicate drying and dehydration is silica gel, it has a strong adsorption capacity, can absorb various gases, so commonly used as the adsorbent, desiccant and carrier of a portion of the catalyst.
