Silicon metal is a grey and shiny semiconductor metal, also known as crystalline silicon or industrial silicon, and is mainly used as an additive for non-ferrous alloys. Silicon metal is produced from quartz and coke in an electric furnace, and the content of the silicon element is about 98% (in recent years, with a content of 99.99%, Si is also called silicon metal), and the other impurities are mainly iron, aluminium, calcium, and so on. The classification of metallic silicon is according to the content of iron, aluminium, and calcium; silicon metal can be divided into different grades such as 553, 441, 411, 3303, 2202, and 1101.

Silicon metal is silver gray or dark gray powder with metallic luster, which be of high melting point, good heat resistance, high resistivity and superior oxidation resistance, it's called "industrial glutamate", which is an essential basic raw material in hi-tech industry.

Application

It is a key constituent in products, like cement, electrical steel, ceramic, concrete and glass. It's metallic form called ferro silicon is widely used as a deoxidizing agent in the carbon and stainless steel production. Ferro silicon is highly demanded and used in steel smelting. Other than steel making, ferro silicon can be used to refine high purity magnesium, and produce ductile iron and magnesium ferro silicon. It can also make silicon steel and ferrous silicon alloys that are resistant to corrosion and heat.

Metallurgical silicon is used as an alloying agent in aluminum casting and resultant aluminum-silicon (Al-Si) is used to make light in wight and strong car components that are better than components cast from pure aluminum. Chemical industry uses metallurgical silicon in making fumed silica, silanes and silicone.
