· JVASP-131776· Dy8Si

Dy8Si is an intermetallic ceramic compound containing dysprosium and silicon, belonging to the rare-earth silicide family. This material is primarily of research and development interest for high-temperature applications where its thermal stability and potential oxidation resistance are leveraged. Dysprosium silicides are investigated for aerospace thermal barrier coatings, nuclear fuel cladding, and advanced refractory applications where conventional ceramics reach performance limits, though industrial adoption remains limited compared to established alternatives like yttria-stabilized zirconia.

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.
