· YRe4Si2

YRe4Si2 is an intermetallic ceramic compound combining yttrium, rhenium, and silicon, representing a rare-earth refractory material class. This material belongs to the family of high-temperature intermetallics and is primarily of research interest for extreme-environment applications where conventional superalloys and ceramics reach their limits. Its dense structure and refractory composition position it as a candidate for advanced aerospace and energy systems requiring materials that maintain stability at very high temperatures.

Regulatory Screening

Environmental

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.
