Silicon metal is a grey and shiny semiconductor metal, also known as crystalline silicon or industrial silicon, and is mainly used as an additive for non-ferrous alloys. Silicon metal is produced from quartz and coke in an electric furnace, and the content of the silicon element is about 98% (in recent years, with a content of 99.99%, Si is also called silicon metal), and the other impurities are mainly iron, aluminium, calcium, and so on. The classification of metallic silicon is according to the content of iron, aluminium, and calcium; silicon metal can be divided into different grades such as 553, 441, 411, 3303, 2202, and 1101.

What is silicon metal grade 2501?
Silicon Metal grade 2501 is one of the silicon grades which is widely used in industries.

Silicon metal 2501 specifications:
The diameter of silicon metal 421 is 10-50 mm, 90% minimum, or according to customers’ requirements.

Uses of Silicon metal 2501 :
The main purpose of silicon metal is the additive as a non-iron-based alloy. The content of silicon in the earth crust is 27.7%, the second largest element in earth curst, the most abundant element in the earth's crust – oxygen and silicon – combine to silica sio2, accounting for 87% of the total mass of the crust. Silicon is a nonmetallic element, grey, metallic color, hard and brittle. Atomic weight 28.80; density is 2.33g/m3; the melting point is 1410℃; the boiling point is 2355℃; resistivity was 2140Ω.m. Semiconductor silicon, which use for production of semiconductor device, is a high purity silicon metal, with polycrystalline and monocrystalline form.

Purpose of Silicon Metal:
1. Use for Al alloy product: could be added in aluminium alloys, to enhance the strength of the alloy, increase its anti-oxidation and corrosion resistance, decrease its density and coefficient of thermal expansion, meliorate its casting performance, and make the alloy have high impact resistance and pressure resistance.

2. Used for cold-rolled silicon steel product: After adding silicon metal in steel, it could greatly improve the magnetic properties of steel, increase its permeability, reducing the hysteresis and eddy current losses.

3. Use for high-purity semiconductor products: Due to the high melting point of silicon, good thermal stability, large band gap, and rich in resources, with technology has been improving, integrated circuits and large-scale integrated circuits made from silicon semiconductors have been used in various fields, the demand is growing up year by year.

4. Use for organic silicon products: silicone, silicon resin, and silicone oil Silicone: which maintains flexibility in the range of-700℃ to 2000℃, could be used for high-temperature gaskets and cold insulation materials. Silicon resin: For the production of insulating paint, heat temperature of 180 ~ 2000℃, can also be used for the production of high-temperature coatings. Silicone oil: For the production of senior lubricant, polishing agent, fluid spring, and dielectric liquid, also could be processed into a colourless transparent liquid, and sprayed on the building for waterproofing. Silicon metal is more and more widely used in organic silicon industry, the usage amount tends to exceed the aluminium alloy industry.

5. Use for the heat-resisting material product: For the production of Si3N4, heat-resistant, wear-resistant, and corrosion-resistant. Making the coated material can prevent oxidation. Siliconized steel surfaces can improve the corrosion resistance of the steel.
