产品介绍(Products Introduction )
一、 金属硅
工业硅又称金属硅和结晶硅，呈银灰色结晶状，性硬且脆，采用含SiO2 98.5%以上的石英石和其他材料熔炼而成。工业硅的用途较其广泛，是一种基础的工业原料，在许多行业和领域有着广泛的应用，主要用于航天、航空、电子、化工、冶炼、保温耐火材料等行业。用于生产硅橡胶、硅树脂、硅油等**硅，制造高纯半导体与配制合金等。
Ⅰ Metallic Silicon
Metallic silicon which is also named as industrial silicon is silver-grey color, in crystal shape with the features of stiff and fragile. Aquartz contenting 98.5% SiO2 is the main material in producing metallic silicon. Metallic silicon has a wide range of application; it’s a kind of basic raw material in industry. This material is also applied to various fields, mainly used for aerospace, aviation, electronic, smelting and chemical industries, thermal insulating material and fire resisting material. Metallic silicon is used to produce organic silicon, such as silicone rubber, silicone resin, and silicon oil. Furthermore, metallic silicon is applied to super-purity semiconductor and alloys.

Ⅱ Silica Fume
Commodity: Silica fume is grey powder and packed in woven bag of 25 kg each (±0.25). The produce is qualified for the YB/T115-1997 standard.
Description: silica fume (scientific name; Micro silica or silica fume) is a kind of silica dioxide (SiO2) without fixing shape. It’s the collection of flue gas from silica steam oxidation by the special designed system of environmental protection. The product is packed in 25kg per bag, so that the shipment will be more convenient.
Application: Mainly used for concrete to improve its performance. With silica fume, the concrete will have the features of super strength(≥C70), corrosion resistance, anti-freeze. Then, this kind of special material is suit for building dam harbor, railway and super high-rise building. Silica fume the comprehensive performance of materials and promote strength and duality of products, when it is applied to refractory, ceramics, painting, rubber and other High Polymer Materials.
