About Ferro Silicon
Ferro Silicon is formed by combining Iron and Silicon with a usual Silicon content of over 70% for steel application. This additive is used with other ferro alloys in the deoxidising process of steel, as well as in the production of Silicon itself. Ferro Silicon is used in the production of cast iron, as Ferro Silicon can accelerate graphitisation. Ferro Silicon replaces the need for Ferro Manganese, Spiegeleisen and Calcium Silicide in the manufacturing process.
Properties of Ferro Silicon
Ferro Silicon has a melting point of 1200°C to 1250°C with a boiling point of 2355°C and contains about 2% of Calcium and Aluminium. Ferro Silicon, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resultant alloy. Some of the primary benefits of adding Ferro Silicon to an alloy is to improve the corrosion resistant properties and to improve the high temperature heat-resistance of the new alloy.
Production of Ferro Silicon
Silica (or sand) is mixed with coke and then a reduction process takes place in the presence of mill scale, scrap or another source of Iron. Steel grade Ferro Silicon is produced in an electric arc furnace but a blast furnace can be used for Ferro Silicon with a lower Silicon content (e.g. 15% Si).
Uses of Ferro Silicon
The main applications of Ferro Silicon are in Carbon Steel and Stainless Steel production. In the steel industry, it is used as a deoxidising agent and it is used as an inoculant in cast iron production. It is also used in the Pidgeon process to produce Magnesium from Dolomite. Applications in the production of other alloys include the manufacture of Silicon Steel for electric motors and cores as well as coatings used during arc welding.
One useful by-product of the production process is Silica Fume, which is later added to concrete mixes to improve compressive and bonding strength there. Silica Fume is available from Westbrook in various grades.

Ferro Silicon FAQs
What raw materials are used to produce Ferro Silicon?
The raw materials used to produce Ferro Silicon include silica (SiOâ‚‚ - usually in the form of quartz) and iron sources such as scrap iron or iron oxide. Additionally, reducing agents like coke or charcoal are used during the Ferro Silicon production process. The materials are smelted in an electric arc furnace, where the silica is reduced to silicon, which then combines with iron to form Ferro Silicon.
What is the difference between Silicon Metal and Ferro Silicon?
Silicon Metal and Ferro Silicon differ in composition and applications. Metallurgical Silicon Metal, with 98-99% Silicon content, is used in Aluminium alloys to make them strong and light. Ferro Silicon is an alloy of Iron and Silicon containing 15-90% Silicon (usually >70% in Western steel production) and is primarily used as a deoxidising agent in steelmaking and to enhance the properties of cast iron and other alloys.
