Silicon metal price

Silicon metal block, also known as crystalline silicon or industrial silicon, is a kind of industrial purification of elemental silicon, can be used to produce high purity semiconductor materials, silicon metal block grade of 99.999(5N). It is mainly used in the production of organosilicon, which is used in the 3C industry. It can also be used as an additive in non-ferrous alloys in many aspects, such as the manufacture of special purpose alloys. Silicon block is a kind of non-metallic element, blue-gray, gold, hard and brittle, the content of silicon accounts for about 26% of the mass of the Earth's crust, commonly used brand silicon block is usually classified according to the content of iron, aluminum, calcium three kinds of primary impurities contained in silicon metal. According to the content of iron, aluminum and calcium in silicon metal block, silicon metal can be divided into 553, 441, 411, 421, 3303, 3305, 2202, 1101 and other different grades.


Large quantities of silicon are used for tempering to form ferro silicon alloys, used as alloying elements in the iron and steel industry, and as reducing agents in various metal tempering processes. Silicon block is still an important component of aluminum alloy, most cast aluminum alloy contains silicon, it is the electronic industry of ultra-pure silicon material. Electronic devices made of ultra-pure semiconductor monocrystalline silicon have the advantages of small size, light weight, good reliability, long service life and so on, so silicon metal powder is a good product. In the organosilicon chemical industry, the industrial silica powder is the basic material for the synthesis of organosilicon polymer, so as to improve the high temperature resistance of products. Industrial silicon wafers are widely used in high-tech fields and are essential raw materials for integrated circuits and electronic components. Silicon metal block is a kind of silicon metal, but it is powdered in physical form. Metallurgical data in China are relatively complex, and some metal elements can be mixed to achieve binary alloy and multivariate alloy data, so that they have different functional characteristics.
