Product Description
The classification of metallic silicon is usually based on the content of iron, aluminum and calcium. According to the content of Fe, AL and CA in silicon metal, silicon metal can be divided into 553,441,411,421,3303,3305,2202,2502,1501,1101 and so on. In industry, metallic silicon is usually made from carbon silicon dioxide in an electric furnace. Chemical equation: Silicon from SIO2 + 2C → SI + 2CO is 97-98% pure silicon, called metallic silicon. After melting and recrystallization, 99.7 ~ 99.8% silicon metal was obtained by removing impurities with acid.

Application:

1. Used in aluminum: An additive to aluminum alloys, metal silicon is used to increase the fluidity and tenacity of Aluminum and its alloys, which enjoy good castability and weldability accordingly. 
2. Used in organic chemicals:metal silicon is used in manufacturing a number of sorts of silicones, resins, and lubricants. 
3. Used in electronic parts: metal silicon is used in producing monocrystalline and polycrystalline silicon of high purity for electronic parts, such as semi conductors, etc.
