Two Overview of Iron Silicide 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. At room temperature, it will form rhombohedral crystals (β-phase), and when heated to 970°C, it will transform into tetragonal α-phase. Iron disilicide is a gray powder, odorless, tetragonal, and insoluble in water. Iron disilicide (FeSi2) is a semiconductor material with a direct band gap (0.85-0.87eV), with high light absorption coefficient, high Seebeck coefficient, high working temperature and high oxidation resistance.
Iron disilicide is an inorganic silicon compound with a molecular formula of FeSi 2 and a molecular weight of 119.975. It is a gray powder, odorless, tetragonal crystal. Inorganic substances, insoluble in water, can be used as hydrogen catalytic oxidation and methanation catalysts, specifically as deoxidizers for welding fluxes, humidity sensors, FeSi₂ thermocouples, thermoelectric solar cells.
How to produce iron disilicide FeSi2 powder?
Through the direct silicide method, the supported ferrosilicon and a new type of catalytic material were successfully synthesized, and the host and iron oxide precursor loading types were gradually eliminated through the co-precipitation preparation method, and then the precursor was reduced under reducing conditions. h. In a hydrogen atmosphere at 400°C and passing a SiH4 / H2 gas mixture at a suitable temperature, different phases of silicide were prepared to support ferrosilicon for 15 minutes. The method has the advantages of small particle size, large specific surface area, strong sulfur resistance, catalytic activity and stability of the dibenzothiophene hydrodesulfurization reaction of only one child, and has potential application value.
