Iron silicide is one of several inorganic chemical compounds between iron and silicon .

Extraction and presentation

Iron silicide can be obtained by reacting silicon with iron. Organometallic synthesis methods are also known.

properties

Iron silicide is a gray, odorless solid that is practically insoluble in water. It has a cubic crystal structure with the space group P 2 ₁ 3 (space group no. 198) . Other high pressure variants are also known. Template: room group / 198

use

Iron silicide is used for the deoxidation and alloying of steel melts, alloying of cast iron batches and melts (iron foundries), silicothermal reduction of precious metals ( chromium , molybdenum and vanadium ) and others ( niobium , tungsten ), production of some inoculants and nodulizers by alloying (melting). High-purity iron silicide is used for the production of high-permeability steel for electrical transformers, for the production of FeSiMn, FeSiN and SiMn alloys. It is also used as a metal additive.
