· JVASP-141911· Si3Ru5

Si₃Ru₅ is a ceramic intermetallic compound combining silicon and ruthenium, belonging to the family of refractory metal silicides. This material is primarily investigated in research contexts for high-temperature structural applications where extreme thermal stability and oxidation resistance are critical, though it remains largely experimental rather than widely commercialized. The ruthenium-silicon system offers potential advantages over traditional silicide ceramics in aerospace and energy sectors, though manufacturing complexity and material cost limit current industrial adoption.

Regulatory Screening

Environmental

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.
