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.
Silicon Metal
is available as disc, granules, ingot, pellets, pieces, powder , rod, sputtering target, wire, and in numerous other forms and custom shapes. Ultra high purity and high purity forms also include metal powder.
