Ferro Silicon is a ferroalloy, an alloy of iron and silicon with medium proportion of silicon content between 15 and 90 weight percent. It possesses a high proportion of iron silicides. Ferrosilicon is manufactured by way of reduction of Silica or sand with coke in presence of iron. Most prominent sources of iron here are scrap iron, mill scale. Ferro Silicon with silicon content up to about 15% is manufactured in blast furnaces lined with acid fire bricks. Ferro Silicon with higher proportion of silicon content is produced in electric arc furnaces. The usual formulations on the market available these days are Ferro Silicon with 15%, 45%, 75%, and 90% silicon. Micro silica is a useful byproduct produced during the process of making Ferro Silicon.


A mineral called Perryite is similar to ferrosilicon, with its composition Fe5Si2. When it comes into contact with water, ferrosilicon may slowly produce Hydrogen gas. The reaction, which is triggered up in the presence of base, is used for hydrogen manufacturing. The melting point and density of this Ferro alloy is dependent on its silicon content. Ferrosilicon is ...
... extensively used by the military or defense personnel to quickly produce hydrogen for balloons. The chemical involved in this reaction uses sodium hydroxide, ferrosilicon, and water. It has been practiced by military people since the time of World War 1.


Ferro Silicon is used as a source of getting silicon to reduce metals from their oxides and for deoxidizing steel and other such ferrous alloys. This thing helps preventing the loss of carbon from the molten steel. This particular Ferro alloy is also used for making other significant Ferro Alloys used extensively in an array of industries. It helps manufacturing corrosion-resistant and high-temperature resistant Ferrous Silicon alloys as well as Silicon for electromotor and transformer cores. All these are in good demand in several important industries across nations. In the production of cast iron, ferrosilicon is employed for inoculation of the iron to boost graphitization. Ferrosilicon is a basis for the production of pre-alloys like magnesium ferrosilicon (MgFeSi), required for the manufacturing of ductile iron. Ferro Silicon also plays a significant role t as an additive to cast irons for the purpose of controlling the initial content of silicon.


In Arc Welding field also this Ferro alloy has got some purpose to serve like as coatings in some electrodes. Magnesium ferrosilicon is very vital in the production of nodules that impart flexibility to the ductile iron. This makes cracking more difficult that would not have been possible if something else were used. Ferrosilicon is also instrumental and extensively employed in the Pidgeon process to make magnesium from dolomite. Last but certainly not the least, treating high-silicon ferrosilicon with hydrogen chloride is the foundation of the industrial synthesis of Trichlorosilane.


Thus it can be understood well how lucrative position the Ferro Silicon Manufacturer India can enjoy if they can provide fine quality this particular Indian Ferro alloys to foreign markets. Global markets look forward to avail this raw material in abundance from Indian markets.
