Fe0.998Co0.002Si2 is an iron-cobalt silicide intermetallic compound with cobalt as a minor alloying addition to an iron disilicide base. This material belongs to the family of transition metal silicides, which are typically evaluated for high-temperature structural applications and electronic device applications due to their ceramic-like hardness combined with metallic conductivity. The minimal cobalt doping (0.2%) suggests this is likely a research composition designed to modify the properties of iron disilicide for specific engineering requirements, such as improving oxidation resistance, thermal stability, or electrical characteristics compared to undoped Fe-Si2.
