· Si1 Ni3

Si₃Ni₄ is an intermetallic compound belonging to the silicon-nickel system, representing a ceramic or ceramic-composite material that combines silicon's hardness with nickel's toughness. This material is primarily of research and development interest for high-temperature structural applications where improved fracture resistance over monolithic ceramics is desired, such as in aerospace engine components and wear-resistant coatings. Its notable advantage over conventional silicon carbide or alumina ceramics is enhanced mechanical reliability at elevated temperatures, though industrial production remains limited compared to established ceramic alternatives.

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.
