· Si4 Sc4 Ru2

Si₄Sc₄Ru₂ is an experimental intermetallic semiconductor compound combining silicon, scandium, and ruthenium in a defined stoichiometric ratio. This material family falls within research-stage high-entropy and transition-metal silicides, which are being investigated for potential applications requiring thermal stability and electronic properties beyond conventional semiconductors. Such compounds remain largely in academic development and are not yet widely deployed in commercial products, but represent exploration into materials combining refractory metal hardness with semiconductor functionality.

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.
