供應有色金屬矽——通氧金屬矽價格便宜

金屬矽定義：

金屬矽又稱結晶矽或工業矽，其主要用途是作為非鐵基合金的添加劑。矽是非金屬元素，呈灰色，有金屬色澤，性硬且脆。矽的含量約占地殼質量的26%；原子量為28.80；密度為2.33g/m3；熔點為1410C；沸點為2355C；電阻率為2140Ω.m。

金屬矽的牌號：

按照金屬矽中鐵、鋁、鈣的含量，可把金屬矽分為553、441、411、421、3303、3305、2202、2502、1501、1101等不同的牌號。

金屬矽的附加產品:

包括矽微粉,邊皮矽，黑皮矽，金屬矽渣等。其中矽微粉也稱矽粉、微矽粉或矽灰，它廣泛應用於耐火材料和混凝土行業

金屬矽的用途：

金屬矽（Si）是工業提純的單質矽，主要用於生產有機矽、制取高純度的半導體材料以及配制有特殊用途的合金等。

（1）生產矽橡膠、矽樹脂、矽油等有機矽

矽橡膠彈性好，耐高溫，用於制作醫療用品、耐高溫墊圈等。

矽樹脂用於生產絕緣漆、高溫塗料等。

矽油是一種油狀物，其粘度受溫度的影響很小，用於生產高級潤滑劑、上光劑、流體彈簧、介電液體等，還可加工成無色透明的液體，作為高級防水劑噴塗在建築物表麵。

（2）制造高純半導體

現代化大型集成電路幾乎都是用高純度金屬矽制成的，而且高純度金屬矽還是生產光纖的主要原料，可以說金屬矽已成為信息時代的基礎支柱產業。

（3）配制合金

矽鋁合金是用量最大的矽合金。矽鋁合金是一種強復合脫氧劑，在煉鋼過程中代替純鋁可提高脫氧劑利用率，並可凈化鋼液，提高鋼材質量。矽鋁合金密度小，熱膨脹系數低，鑄造性能和抗磨性能好，用其鑄造的合金鑄件具有很高的抗擊沖擊能力和很好的高壓致密性，可大大提高使用壽命，常用其生產航天飛行器和汽車零部件。

矽銅合金具有良好的焊接性能，且在受到沖擊時不易產生火花，具有防爆功能，可用於制作儲罐。

鋼中加入矽制成矽鋼片，能大大改善鋼的導磁性，降低磁滯和渦流損失，可用其制造變壓器和電機的鐵芯，提高變壓器和電機的性能。

隨著科學技術的發展，金屬矽的應用領域還將進一步擴大

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 industry.

(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:
