Iron silicide (FeSi or FeSi2) is an intermetallic compound, a silicide of iron, utilised in various industries due to its semiconducting properties, thermal stability, and metallurgical benefits. In the metallurgical sector, it functions as a deoxidising agent in steelmaking and an alloying element to improve the mechanical properties of iron and steel. It is also used in thermoelectric devices for waste heat recovery, due to its high-temperature performance in generators for power plants. Additionally, iron silicide powder enables sputtering targets and thin-film production for semiconductors and electronics, supporting high-density sintering with low oxygen content. It also finds roles in high-temperature structural components for aerospace and turbines, photovoltaics, catalysis, and anti-corrosive batteries.

Iron silicide market growth is propelled by rising demand in electronics and semiconductors, as sputtering targets for thin-film deposition in devices and photovoltaics. Its expansion in thermoelectric applications for waste heat recovery in power plants and industrial processes drives adoption due to its high-temperature stability and efficiency. The automotive, aerospace, and high-temperature materials sectors contribute to the demand, fuelled by needs for advanced alloys, structural components in turbines, and lightweight materials with superior mechanical properties.

Additionally, growth in renewable energy sectors like solar cells and emerging battery technologies boosts market growth, along with steady metallurgy uses in steel deoxidation. However, purity levels, specified as 99%+ metals basis with low oxygen content, directly affect industrial iron silicide procurement for applications like sputtering targets or high-density sintering in semiconductors, as higher purity reduces defects in thin films.

Raw Material for Iron Silicide Production

According to the Iron Silicide production plant project report, the various raw materials for Iron Silicide production include iron sesquioxide (Fe2O3), elemental silicon, and active metals like magnesium or lithium.

Production Process of Iron Silicide

The extensive Iron Silicide production cost report consists of the following major industrial production process:

1. Production via a solid-state reaction: The production process of Iron silicide occurs via a solid-state reaction route using iron sesquioxide (Fe2O3), elemental silicon, and active metals like magnesium or lithium as reactants in a stainless-steel autoclave at 650 degree Celsius. The process begins by mixing the powders in stoichiometric ratios tailored to the target phase, with the choice of active metal (Mg or Li) influencing selectivity. The sealed autoclave is heated to reaction temperature for several hours, allowing exothermic reduction of Fe2O3 to iron intermediates that react with silicon, producing pure iron silicide after cooling, washing to remove byproducts (e.g., MgO or Li2O), and drying.

Properties of Iron Silicide

Iron silicide is an intermetallic compound that has a cubic crystal structure (P213 space group) with no inversion centre, leading to helical magnetic ordering at low temperatures and narrow-bandgap semiconducting behaviour (resistivity ~10 kΩ·cm at room temperature). It shows ferromagnetic properties with a narrow symmetric Si L23 emission peak at ~90 eV, high hardness, and metallic lustre, while both phases show thermal stability up to 1000 degree Celsius and densities around 7.0-7.5 g/cm³. These materials possess metallic conductivity in bulk form, with FeSi displaying asymmetric emission spectra indicating sp-d orbital interactions. Iron silicide resists oxidation at high temperatures due to stable Si-Fe bonds but reacts with strong acids to form iron salts and silicates. It remains inert to most alkalis. The FeSi phase shows paramagnetic tendencies at ambient conditions, shifting to helical magnetism below 50 K, while Fe3Si is ferromagnetic with atomic moments up to 0.43 μB per Fe atom in related structures. Additionally, low oxygen solubility (<5 at.%) ensures high purity in powders, supporting applications requiring minimal contamination.
