Si2Ni
metal· JVASP-20751· Si2Ni
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.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
