· Si4 Co18 Th2

Si₄Co₁₈Th₂ is a complex intermetallic compound combining silicon, cobalt, and thorium in a defined stoichiometric ratio. This material falls within the family of advanced intermetallics and is primarily of research interest rather than a widely commercialized engineering material. The incorporation of thorium—a radioactive element with high density and thermal properties—suggests potential applications in specialized high-temperature or nuclear contexts, though the practical engineering use of thorium-containing alloys remains limited due to handling, regulatory, and material-processing constraints.

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.
