Application range and synthesis method of FeSi2 powder of iron disilicide

Iron silicide is an inorganic substance with a chemical formula of FeSi₂, gray powder, odorless, tetragonal crystal, insoluble in water, and can be used as a catalyst for hydrogen catalytic oxidation and methanation, specifically as a deoxidizer for welding flux, humidity sensor, FeSi₂ thermocouple, thermoelectric solar cell.

How to synthesize iron disilicide

The iron powder and the silicon powder with a molar ratio of 1:2 are evenly mixed and eutecticized or sintered in a vacuum or an inert atmosphere.

Ecological data of iron disilicide

Usually it is not harmful to water. If there is no government permission, do not discharge the material into the surrounding environment.

Summary of FeSi2 FeSi2 powder

The chemical form of iron disilicide is FeSi2, which is an intermetallic compound and a kind of iron silicide, which exists in nature as a rare mineral. Rhombic crystals (β-phase) are formed at room temperature, which transform into tetragonal α-phase when heated to 970°C. Iron disilicide is a gray powder, odorless, tetragonal crystal system, insoluble in water. Iron disilicide (FeSi2) is a semiconductor material with a direct band gap (0.85-0.87eV), with high absorption coefficient, high Seebeck coefficient, high working temperature and high oxidation resistance.

Iron disilicide is an inorganic silicon compound with a molecular formula of FeSi2 and a molecular weight of 119.975. It is a gray powder, odorless, tetragonal crystals.
