· ReSi2

ReSi₂ is a refractory intermetallic compound composed of rhenium and silicon, belonging to the family of transition metal disilicides. It is primarily investigated as a high-temperature structural material and represents an active area of materials research rather than a widely commercialized industrial product, with potential applications in extreme thermal environments where conventional superalloys reach their limits.

Export Control

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.
