Product Details

FeSi Powder

1).Ferro silicion or ferrosilicium, is a ferroalloy an alloy of iron and silicon with between 15 and 90% silicon.

2).It contains a high proportion of iron silicides.

3).Ferro silicion or ferrosilicon melting point is about 1200 °C to 1250 °C with a boiling point of 2355 °C.

4).It also contains about 1 to 2% of calcium and aluminum.

5).The usual formulations on the market are ferrosilicon with 15%,45%, 60% 65% 72% 75%, and 90% of silicon.

6).The remainder is iron, with about 2% of other elements like aluminum and calcium.

7).CAS number is [8049-17-0].

APPLICATION

1) Widely applied to refractory material and power metallurgy industry to improve the heat resistance, wear

resistance and oxidation resistance.

2) In the chemical line of organic silicon, industrial silicon powder is basic raw material that high polymer of

organic silicon formatting.

3) Industrial silicon powder is sublimated into monocrystalline silicon, which is widely used in highttech field as an

essential raw material for integrated circuit and electronic element

4) In metallurgy and foundry line, industrial silicon powder is regarded as to be iron base alloy additive, the alloy

pharmaceutical of silicon steel, thus improve the steel hardenability
