· Si2Ni6B

Si₂Ni₆B is an intermetallic compound combining nickel, silicon, and boron—a hard, brittle metallic phase typically found as a constituent in nickel-based alloys and composite materials rather than as a standalone engineering material. This compound is primarily of research and development interest for its potential in wear-resistant coatings, high-temperature applications, and strengthening phases in superalloys, though industrial use remains limited compared to conventional nickel alloys. Engineers would consider Si₂Ni₆B primarily as a reinforcement phase or surface treatment component in specialized applications requiring enhanced hardness and thermal stability.
