![]() ![]() Hence adequate protection is needed from accidentally inhaling or ingesting the material. Toxic and flammable gases are produced when this alloy reacts with moisture, bases and acids. The alloy can be hazardous to human health. In this process, magnesium can be derived from dolomite.įerrosilicon is a toxic, irritant and combustible substance. Ferrosilicon is an important component in Pidgeon process.Ferrosilicon is used in the manufacturing of Magnesium ferrosilicon and other similar pre-alloys. Magnesium ferrosilicon is used for modifying molten malleable iron.It is used as a source of silicon as well as to produce high-temperature resistant and corrosion-resistant ferrous silicon alloys.Ferrosilicon is also sometimes used as a component in electrode coatings for arc welding.It is used for making silicon steel that are used in transformer cores and electromotors.Ferrosilicon is used in the manufacturing of semiconductors.It is used to manufacture silicon copper in the chemical industry.Ferrosilicon is used as a source of pure silicon in the electric industry.It is also used for deoxidization and coating in steel melting. The alloy is used as a basic raw material for inoculation, adjusting, suspending, mineral processing and in the melting rod industry.Ferrosilicon is extensively used in the metallurgical industry for the processes of atomization, casting, melting and heavy media separation reactions.This alloy is also used in the manufacturing of other ferroalloys.This helps to prevent loss of carbon from molten steel. Ferrosilicon is used in deoxidizing steel as well as other ferrous alloys. ![]() The various uses of this alloy are discussed below: For FeSi 75, the specific gravity is 3.01. Specific Gravity: Specific Gravity of ferrosilicon varies with the proportions in which the two chemical substances are mixed. Solubility: Ferrosilicon may react with water to produce hydrogen.Ĭombustibility: The dust particles of Ferrosilicon are combustible. Odor: Odorless can be dangerous when inhaled. The density of FeSi 75 is 2.8 g/cm 3 and FeSi 90 has a density of 2.4 g/cm 3.Īppearance: The shape of ferrosilicon powder particles can be spherical or irregular, like lumps, crushed or milled.Ĭorrosivity: It is resistant to corrosiveness and abrasiveness.Ĭolor: The color of Ferrosilicon varies between silvery grey and dark grey. FeSi 90 contains 90% silicon and its melting point ranges between 1210☌ and 1380☌.īoiling Point: The boiling point for this substance is 2355☌.ĭensity: The density of Ferrosilicon is different for different ratios of alloy compositions. FeSi 75 contains 75% silicon and its melting point ranges between 1210☌ and 1315☌. FeSi 45 contains 45% silicon and its melting point ranges between 1215☌ and 1300☌. Melting Point: The melting point of this substance varies with the content of silicon. Molecular Weight: The molecular weight for this alloy is 28.0855 g/mol. The physical and chemical properties of Ferrosilicon are listed below: ![]() Ferrosilicon Chemical and Physical Properties Other constituents like calcium and aluminum have a presence of around 2%. Ferrosilicons having a proportion of 15%, 45%, 75%, and 90% silicon can be found the rest is comprised of iron. Microsilica is an important byproduct obtained from this reaction.įerrosilicons of varying silicon content are found in the worldwide market. Large quantities of silica are required for preventing silicon carbide formation. These small pieces are crushed further to obtain the required size. The hot liquid alloy is then collected in a sandbed, cooled and broken into small pieces. Ferrosilicons having 15% silicon content can be derived from blast furnaces using acid fire bricks.Īnother method of obtaining this alloy is to use a submerged electric arc furnace for melting quartz, steel scrap together with a reductant. Ferrosilicon can be produced by reducing sand or silica with coke and reacting it with iron derived from scraps or millscale. ![]()
