Si2W3
metal· JVASP-150801· Si2W3
Si₂W₃ is a silicide intermetallic compound combining silicon and tungsten, belonging to the family of refractory metal silicides. This material exhibits high stiffness and density, making it of interest in high-temperature and wear-resistant applications where conventional alloys reach their limits. Si₂W₃ remains largely a research-phase material; its practical industrial adoption is limited, but the silicide family is valued in aerospace, automotive, and materials science communities for applications requiring thermal stability and hardness.

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.
