Products Description
Can be used for metallurgy deoxidation, aluminum alloy.
As the main raw material of making polycrystalline silicon and monocrystalline silicon.
Used to synthesize organic silicon monomer.
Can be used inthe third generation semiconductor, silicon based anode material, high purity silicon nitride, target material, high purity silica sol and other emerging industries.
One of the uses of silicon metal is to make cermet composite materials, which can make up for the shortcomings of metals and ceramics, and have the advantages of high temperature resistance, toughness, and cutting ability. Therefore, in the production of refractory materials and powder metallurgy, adding an appropriate amount of metal silicon powder can greatly improve the high temperature resistance of metal silicon powder. Silicon metal has a wide range of applications in the field of electronics, such as high purity silicon metal for communication fiber. In addition, it can also be used to make abrasive materials, fillers and coatings. In addition to electronics, silicon has applications in many other fields, such as rubber, plastics and coatings. In short, the wide application of silicon makes it play an important role in modern industry. In medical applications, metallic silicon has a wide range of applications. For example, researchers from the Department of Bioengineering at the National University of Singapore's Faculty of Engineering have developed a new technique capable of converting infrared light into ultraviolet and visible light via silica nanoparticles, paving the way for non-invasive therapies for deep tumors. The technology is able to inhibit tumor growth and is the world's first non-invasive photodynamic therapy using nanoparticles to treat deep tumors. Silicon is the eighth most abundant element in the universe and the second most abundant element in the Earth's crust, making up 26.4% of the total mass of the Earth's crust, after oxygen.
Product parameters
The classification of silicon metal is usually classified by the content of the three main impurities of iron, aluminum and calcium contained in the silicon metal composition. According to the content of iron, aluminum and calcium in metal silicon, metal silicon can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and other different grades.
In industry, metallic silicon is usually produced by carbon reduction of silicon dioxide in electric furnaces. Chemical reaction equation: SiO2 + 2C → Si + 2CO The purity of silicon produced in this way is 97~98%, which is called metallic silicon. Then it is melted and recrystallized, and impurities are removed with acid to obtain metallic silicon with a purity of 99.7~99.8%.
