Physical and Chemical Properties | Iron (II) silicide is an inorganic silicon compound with a molecular formula of FeSi, a molecular weight of 119.975, a gray powder, odorless, tetragonal. It can be used as a catalyst for catalytic oxidation of hydrogen and methanation, in particular as a deoxidizer for a welding flux, a humidity sensor, an FeSi thermocouple, and a thermoelectric solar cell. |
Use | Iron silicide can be used as a catalyst for the catalytic oxidation and methanation of hydrogen. Deoxidizer, humidity sensor, FeSi2 thermocouple, thermoelectric solar cell used as welding flux. |
TSCA | Yes |
when silica and ferric oxide are reduced with carbon, the product iron is formed by interaction with silicon.
