· Si3 Ru1

Si3Ru1 is an experimental intermetallic compound combining silicon with ruthenium, belonging to the family of transition metal silicides. This material is primarily of research interest for high-temperature applications where its ceramic-like rigidity and potential thermal stability could provide advantages over conventional semiconductors or refractory metals. While not yet commercialized at scale, silicides in this family are investigated for electronic devices operating in extreme environments, catalytic applications, and as barrier materials in microelectronics—areas where the combination of metallic and ceramic properties offers novel possibilities.

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.
