CoSi is an intermetallic compound combining cobalt and silicon, belonging to the family of transition metal silicides. This material is primarily investigated for high-temperature structural applications and electronic/thermal devices, where its combination of metallic bonding and intermetallic ordering offers potential advantages in stiffness and thermal stability compared to conventional alloys. CoSi and related silicides are of particular interest in aerospace, microelectronics, and thermoelectric research due to their potential to operate at elevated temperatures while maintaining strength, though processing and brittleness remain engineering challenges.
