Silicon metal, also in order to as crystalline silicon or industrial silicon, its main me is as a non-iron-based alloy additives. Its add-on products include: microsilica, silicon edge leather, black silicon, silicon metal slag. Which in the microsilica, named silicon power, micro silica fume or silica fume, and occasion widely made use of in refractory and concrete industry. Silicon metal powder: the basic raw material for silicone polymer materials, such as: silicon the metallurgical foundry, smelting, chemical products, refractories, aluminum and aluminum alloy production and other industry.
Crystalline silicon is steel gray, is bestowed upon atomic crystal, hard and shiny, with semiconductor the earth. The chemical nature of the silicon is lively, at high temperatures can be combined with oxygen and other elements, don't dissolve in water, nitric acid and hydrochloric acid, dissolved in hydrofluoric acid and lye for built in alloys such as ferrosilicon, silicon, monocrystalline Silicon is a necessary semiconductor material used for manufacturing high-power transistors, rectifiers, solar cells, for instance. Silicon is widely distributed in nature, containing about 27.6% of this Earth's crust, mainly by silica and silicates. The crystalline silicon is dark blue, very brittle, and still is a typical semiconductor. Mit nature is kind of stable. At room temperature, except the hydrofluoric acid, it is not easy to react with other particles.
The high purity single crystalline silicon is a great semiconductor material. A trace amount of a Group IIIA element incorporated in the single crystal silicon, forming a p-type silicon semiconductor; incorporation with regards to a trace involving the aspect of Group VA, the formation of the n-type and p-type semiconductor combination, can be produced of the solar cells, turn the radiation into strength. In the development of energy resources, it is really a promising products.
As the surveys by metal powder supplier, silicon is important materials for cermet and astronautical. Sintered mixture of ceramic and metal, associated with metal-ceramic composites, it is high temperature rich toughness, can be cut, the inherited the respective advantages of metal and ceramic, furthermore to renew both birth defects. Does apply to the manufacture of military weapons, the first space shuttle 'Columbia' can withstand high-speed walk along with the friction heat generated by the dense atmosphere, thanks to the thirty-one thousand silicon watts shell mosaic project.
It can be used for optical fiber communications, the latest modern associated with communication. Slow of a high transparency with a pure silica glass fiber, a laser in the passage from the glass fiber, the total reflection different onward transmission, instead belonging to the cumbersome cable. The high capacity of optical fiber communications, glass fibers like a hair can transmit 256 telephone channels at the same time, also without electricity, magnetic interference, and are not afraid of wiretapping, by using a high quantity confidentiality. Optical fiber communication will make revolutionary changes in the lives of a beings today.
Due on the unique structure of consider silicon, with both the performance among the organic material and inorganic material, using a low surface tension, low viscosity-temperature coefficient, and high compressibility, and high gas permeability basic properties, and working with a high temperature resistance, electrical insulation resistance, oxidation stability resistance, weather resistance, flame retardant, hydrophobic, corrosion-resistant, non-toxic, odorless and physiologically inert and other outstanding features, widely discovered the aerospace, electrical and electronics, construction, transportation, chemical industry, textile, food, light industry, medical industry, The silicone a brand new used in sealing, bonding, lubrication, coatings, surfactants, mold release, anti-foaming, defoaming, waterproof, moisture-proof, inert fillers. The new continued connected with the number and variety of organic silicon, the applications is continue to widen, the development of new chemical materials sector is unique product system, many varieties can halt replaced by other chemicals but essential.
