Si₂Ni is an intermetallic compound consisting of nickel and silicon, belonging to the family of transition metal silicides. This material exhibits the characteristic brittle behavior typical of intermetallic phases, with relatively high stiffness but limited ductility at room temperature. Si₂Ni and related nickel silicides are investigated primarily in research contexts for high-temperature structural applications, wear-resistant coatings, and as reinforcement phases in composite materials, where their thermal stability and hardness offer potential advantages over conventional nickel alloys in demanding environments.
