Metal silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Silicon metal is a product smelted from quartz and coke in an electric furnace. Silicon Metal’s main component silicon content is about 98%. In recent years, 99.99% Si content is also included in metal silicon, and the remaining impurities are iron, aluminum, calcium, etc.
“Metal silicon” (also known as industrial silicon, silicon metallic) is a commodity name that appeared in the mid-1960s. Its appearance is related to the rise of the semiconductor industry. The international practice is to divide commercial silicon into metal silicon and semiconductor silicon. Metal silicon price. Silicon metal is a product smelted from quartz and coke in an electric furnace, and the content of silicon as the main component is about 98%. Semiconductor silicon is used to make high-purity metal silicon for semiconductor devices. It is sold in the form of polycrystalline and single crystal, the former is cheap and the latter is expensive. It is divided into various specifications because of its different uses. According to statistics, in 1985 the world consumed a total of about 500,000 tons of silicon metal. Among them, metal silicon used for aluminum alloys accounts for about 60%, organic silicon for less than 30%, semiconductors for about 3%, and the rest for iron and steel smelting and precision ceramics.
Particle Size Grade and Type Classification of Silicon Metal
Industrial silicon is also called silicon metallic. Industrially, metallic silicon is usually produced by reducing silicon dioxide with carbon in an electric furnace. Chemical reaction equation: SiO2 + 2C → Si + 2CO The silicon purity obtained 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%.
The classification of metal silicon is usually classified according to the content of three main impurities of iron, aluminum, and calcium contained in metal silicon. According to the content of iron, aluminum, and calcium in metal silicon, metal silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101, and so on. The additional products of silicon metallic include micro-silica fume, edge silicon, black skin silicon, metal silicon slag, etc. Among them, micro-silica fume is also called silica fume, silicon metal powder, which is widely used in refractory materials and concrete industries.

Industrial silicon also called silicon metal is silver gray or dark gray metallic luster and is made of quartz and other materials containing more than SiO2 98.50%. silicon metal 3303, silicon metal 1101, silicon metal 2202, silicon metal 421, silicon metal 3303 price. The particle size: 10 – 100mm, 10 – 50mm, 0 – 3mm, 2 – 6mm, and 3 – 10mm, etc.
Pure Silicon Metal
Ultra-pure silicon metal, with no more than a few atoms of impurities per thousand atoms, is the most important semiconductor material. Widely used in computer, microwave communication, optical fiber communication, solar power generation, etc. Semiconductor silicon materials are developing rapidly. The annual consumption of monocrystalline silicon exceeds 2,500 tons, and the consumption of silicon wafers is 2.5 billion square inches. The research and production of silicon materials in my country have also made great progress. The single crystal with a diameter of less than 3 inches has reached the international level, and the cutting, grinding, and polishing processes and equipment have been established. Therefore, my country’s ultra-pure silicon metal has great potential for development.
Silicon metal polysilicon metallurgical silicon, the supply of high-purity metal silicon, polysilicon, monocrystalline silicon 553 411 industrial silicon block, silicon metal particles. The metal silicon component is mainly silicon, so it has similar properties to silicon. Silicon has two allotropes, amorphous silicon, and crystalline silicon. Amorphous silicon is a gray-black powder, which is actually a kind of microcrystal. Crystalline silicon has the crystal structure and semiconductor properties of diamond, with a melting point of 1410°C, a boiling point of 2355°C, a Mohs hardness of 7, and is brittle. Amorphous silicon is chemically active and can burn violently in oxygen. It reacts with halogen, nitrogen, carbon, and other non-metals at high temperatures, and can also react with magnesium, calcium, iron, and other metals to form silicide. Amorphous silicon is almost insoluble in all inorganic and organic acids including hydrofluoric acid, but can be dissolved in mixed acids of nitric acid and hydrofluoric acid. Concentrated sodium hydroxide solution can dissolve amorphous silicon and release hydrogen gas. Crystalline silicon is relatively inactive and does not combine with oxygen even at high temperatures. It is also insoluble in any inorganic and organic acids, but soluble in mixed acids of nitric acid and hydrofluoric acid and concentrated sodium hydroxide solution.
Silicon Metal Usage
Industrial silicon has a wide range of uses and is a basic industrial raw material. It is widely used in many industries and fields, mainly used in aerospace, aviation, electronics, chemical industry, smelting, thermal insulation refractory and other industries.
Use of Silicon Metal
- The silicon block is mainly used for Aluminum Alloy ingot smelting, Automobile hub, cases, etc.
- It is the main raw material of trichlorohydrosilicon, polycrystalline silicon, organosilicon, and silica sol.
- It is the essential ingredients for special steel, stainless steel, silicon steel.
In the aluminum alloy industry, silicon-aluminum alloys are the most used silicon alloys. Silicon-aluminum alloy is a strong composite deoxidizer, which can improve the utilization rate of deoxidizer when replacing pure aluminum in the steelmaking process, and can purify molten steel and improve steel quality. Aluminum used in industries such as automobiles has a considerable demand for industrial silicon, so the development of the automobile industry in a region or country has a direct impact on the rise and fall of the industrial silicon market. Additives for non-ferrous alloys, industrial silicon is also used as an alloying agent for silicon steel with strict requirements, and a deoxidizer for smelting special steels and non-ferrous alloys.
In the chemical industry, it is used to produce silicone rubber, silicone resin, silicone oil, and other silicones. Silicone rubber has good elasticity and high-temperature resistance and is used to make medical supplies, high-temperature-resistant gaskets, etc. Silicone resin is used in the production of insulating varnishes, high-temperature coatings, etc. Silicone oil is an oil whose viscosity is little affected by temperature and is used in the production of advanced lubricants, polishes, fluid springs, dielectric fluids, etc. It can also be processed into a colorless and transparent liquid and sprayed on the surface of buildings as a high-grade waterproofing agent.
Industrial silicon is purified by a series of processes to produce polysilicon and monocrystalline silicon for use in the photovoltaic industry and the electronics industry. Crystalline silicon cells are mainly used in solar rooftop power stations, commercial power stations, and urban power stations with high land costs. It is currently the most mature and widely used solar photovoltaic product. Occupying more than 80% of the world’s photovoltaic market, its demand for metal silicon has grown significantly. Almost all modern large-scale integrated circuits are made of high-purity metalloid silicon, and high-purity metalloid silicon is also the main raw material for the production of optical fibers. It can be said that metalloid silicon has become the basic pillar industry of the information age.
