按照金属硅中铁、铝、钙的含量，可把金属硅分为553、441、411、421、3303、3305、2202、2502、1501、1101等不同的牌号。
金属硅的附加产品:
包括硅微粉,边皮硅，黑皮硅，金属硅渣等。其中硅微粉也称硅粉、微硅粉或硅灰，它广泛应用于耐火材料和混凝土行业
金属硅的用途：
金属硅（Si）是工业提纯的单质硅，主要用于生产有机硅、制取高纯度的半导体材料以及配制有特殊用途的合金等。
（1）生产硅橡胶、硅树脂、硅油等有机硅
硅橡胶弹性好，耐高温，用于制作医疗用品、耐高温垫圈等。
硅树脂用于生产绝缘漆、高温涂料等。
硅油是*种油状物，其粘度受温度的影响很小，用于生产高级润滑剂、上光剂、流体弹簧、介电液体等，还可加工成无色透明的液体，作为高级防水剂喷涂在建筑物表面。
（2）制造高纯半导体
现代化大型集成电路几乎都是用高纯度金属硅制成的，而且高纯度金属硅还是生产光纤的主要原料，可以说金属硅已成为信息时代的基础支柱产业。
（3）配制合金
硅铝合金是用量*大的硅合金。硅铝合金是*种强复合脱氧剂，在炼钢过程中代替纯铝可提高脱氧剂利用率，并可净化钢液，提高钢材质量。硅铝合金密度小，热膨胀系数低，铸造性能和抗磨性能好，用其铸造的合金铸件具有很高的抗击冲击能力和很好的高压致密性，可大大提高使用寿命，常用其生产航天飞行器和汽车零部件。
硅铜合金具有良好的焊接性能，且在受到冲击时不易产生火花，具有防爆功能，可用于制作储罐。
钢中加入硅制成硅钢片，能大大改善钢的导磁性，降低磁滞和涡流损失，可用其制造变压器和电机的铁芯，提高变压器和电机的性能。
随着科学技术的发展，金属硅的应用领域还将进*步扩大

Silicon metal definition:
Silicon metal, also known as crystalline silicon or industrial silicon, its main use is as an iron base alloy additives. Silicon is a non-metallic element, it is gray, metal color, hard and brittle. The content of silicon accounted for about 26% of the mass of the earth's crust; Atomic weight of 28.80; The density of 2.33 g/m3; Melting point of 1410 c; Boiling point of 2355 c; The resistivity of 2140 Ω. M.
Silicon metal grades:
According to the silicon metal iron, aluminum, calcium, divides into the silicon metal 553, 441, 411, 421, 411, 3305, 2202, 2502, 1501, 1101, such as different grades.
The additional products: silicon metal
Including micro silicon powder and silicon, black silicon, silicon metal slag, etc. Silica powder is also called the silicon powder, micro silicon powder and silicon ash, it is widely used in refractory industry and concrete
The purpose of the silicon metal:
metal silicon (Si) is an industrial purification of elemental silicon, mainly for the production of organic silicon, preparing high-purity semiconductor materials and preparation are special-purpose alloy, etc.
(1) the production of silicone rubber, silicone resin, silicone oil, silicone
Silicone rubber has good elasticity, high temperature resistant, used for making medical supplies, high temperature resistant gaskets, etc.
Silicone resin used in the production of insulating paint, high-temperature paint, etc.
Silicone oil is a kind of oil, the viscosity is affected by temperature is very small, for the production of advanced lubricant, polish, fluid spring, dielectric fluid, etc., can also be processed into colorless transparent liquid, as a senior waterproof coating on the surface buildings.
(2) manufacturing high purity semiconductor
Nearly all modern large scale integrated circuit is made of high purity silicon metal, and high purity silicon metal is the main raw material for producing optical fiber, silicon metal has become the basis of the information age, so to speak pillar industr.
(3) based alloy
Silicon aluminum alloy is one of the largest silicon alloy dosage. Silicon aluminum alloy is a kind of compound deoxidizer, instead of pure aluminium in the process of steelmaking deoxidizer can improve the utilization rate, and can purify liquid steel, improve the quality of steel. Silicon aluminum alloy density is small, low thermal expansion coefficient, good casting properties and the anti-wear performance, with its casting alloy castings with high against impact ability and good high density, can greatly improve the service life and commonly used the shuttle and auto parts production.
Silicon copper alloy has good welding performance, and when the impact is not easy to produce sparks, explosion-proof function, can be used for making tanks.
Adding silicon steel made of silicon steel sheet, steel magnetic conductivity can be improved greatly, reduce the hysteresis and eddy current losses, the manufacture of iron core transformer and motor are available, and improve the performance of transformer and motor.
With the development of science and technology, the application field of silicon metal will also further expanded
metal silicon of the main production areas:
Silicon metal are mainly distributed in the southwest of yunnan, sichuan, guizhou, guangxi province, central China's hunan, hubei, fujian region of east China, northeast China is mainly of heihe, heilongjiang province river area, jilin and liaoning, Inner Mongolia, shaanxi and other places also have factory production in qinghai.
