Fe3C–CNF interlayers trap soluble polysulfides and reutilize sulfur species. Fe3C–CNF interlayers also accelerate charge transfer and ion diffusion. Li–S batteries with Fe3C–CNF interlayer have average capacity decay of 0.091%/cycle. A nitrogen and fluorine enriched Fe/Fe3C@C oxygen reduction reaction electrocatalyst for anion/proton exchange membrane fuel cells.

Akeso's lead Fe3C product is a feed additive designed to prevent food poisoning by Campylobacter, a bacteria that causes more cases of foodborne illness in 

Herein, pea-like Fe/Fe3C nanoparticles embedded in nitrogen-doped carbon nanotubes (Fe/Fe3C@NCNTs) are successfully prepared through a direct pyrolysis of the mixture of FeCl3·6H2O and melamine under inert atmosphere. The chemical Fe3C is Upper Bainite-like structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Fe sites.

The resultant Fe3C@NCNF-X catalysts, particularly Fe3C@NCNF-900, showed efficient electrocatalytic performance for ORR in both alkaline and acidic solutions, which are attributed to the synergistic effect between Fe3C and N-doped carbon as catalytic active sites, and carbon shell protects Fe3C from leaching out. Fe3C–CNF-based interlayer is developed for lithium-sulfur battery applications.

Podle formy vyloučení uhlíku se rozlišují dva typy rovnovážného binárního diagramu železo-uhlík: buď diagram metastabilní soustavy Fe-Fe3C nebo diagram stabilní soustavy Fe-C . Diagram metastabilní soustavy, ve které je uhlík vyloučen jako karbid železa Fe 3 C (někdy též cementit), se používá pro oceli a bílou litinu.
