About Iron Disilicide FeSi2 Powder:
Iron Disilicide with the chemical form for FeSi2, is an intermetallic compound, is a kind of silicified Iron, in the form of rare mineral Linzhiite exists in nature. At room temperature, it forms a rhombic crystal (β phase), which transforms to a tetragonal α phase when heated to 970℃. Iron Disilicide is gray powder, odorless, tetragonal, insoluble in water. Iron Disilicide(FeSi2) is a direct bandgap (0.85-0.87eV) semiconductor material with high light absorption coefficient, high Seebeck coefficient, high operating temperature and high oxidation resistance. Kmpass is a trusted global Iron Disilicide FeSi2 Powder supplier. Feel free to send an inquiry about the latest price of Iron Disilicide at any time.

How is Iron Disilicide FeSi2 PowderProduced?
Controlled by direct silicide method successfully synthesized by the body and a load of silicide iron new catalytic materials, success through coprecipitation preparation phase-out of body and ferric oxide precursor load type, and then the preparation of the precursor to the reduction of 3 h under 400 ℃ hydrogen atmosphere, and at the right temperature flux into SiH4 / H2 gas mixture in the preparation of different phase silicide 15 min supported iron silicide. This method has the advantages of small particle size, large specific area, strong sulfur resistance, and the catalytic activity and stability of the dibenzothiophene hydrodesulfurization reaction with only one child, which has potential application value.
Applications of Iron Disilicide FeSi2 Powder:
Iron Disilicide is used as a catalyst for hydrogen catalytic oxidation and methanation.
Iron Disilicide used as a deoxidizer for welding fluxes, humidity sensors, FeSi2 thermocouples, and thermoelectric solar cells.
Iron Disilicide is used in a variety of photoelectric applications such as lithium-ion batteries, light-emitting diodes (LEDs) and solar cells.
