· JVASP-150813· Si2Mo3

Si₂Mo₃ is an intermetallic compound combining silicon and molybdenum, belonging to the refractory metal silicide family. This material is primarily of research and development interest for high-temperature structural applications where traditional steel and nickel alloys reach their limits. Its notable characteristics include excellent hardness and potential for use in extreme thermal environments, though it remains largely experimental rather than established in mainstream industrial production.

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.
