· JVASP-19853· SiNi3

Si₃Ni is an intermetallic compound combining silicon and nickel, belonging to the family of hard, ceramic-like metal compounds used in high-temperature and wear-resistant applications. This material is primarily encountered in research and specialty industrial contexts where extreme hardness and thermal stability are required, often as a coating material or reinforcing phase rather than a bulk structural component. Engineers consider Si₃Ni for applications demanding resistance to oxidation and mechanical wear at elevated temperatures, where traditional steel or nickel alloys would degrade.

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.
