The difference between metal silicon and ferro silicon
The difference between metal silicon and ferrosilicon 65# 72 # 75#
Industrial silicon: Metal silicon is a product refined from silica and carbonaceous reducing agent in a submerged arc furnace. Its main component, silicon, accounts for about 98% (in recent years, silicon with a purity of 99.99% has also been classified as metal silicon). Other impurities include iron, aluminum, calcium, etc.
Ferrosilicon: It is an iron alloy composed of iron and silicon. Industrial silicon includes ferrosilicon, which is a type of industrial silicon.
The biggest difference is that industrial silicon is a metal silicon, while ferro silicon 65# 72 # 75# is an alloy product.
Both are silicon-containing substances.
The difference is: industrial silicon is a simple substance in pure materials and is obtained through industrial smelting. Ferrosilicon is an alloy that melts silicon and iron elements together at a certain ratio under high temperature to form a product that meets specific needs.
