· JVASP-139496· YAlS2

YAlS₂ is an experimental yttrium aluminum sulfide compound, representing an intermetallic or ceramic-like material in the rare-earth metal sulfide family. This compound has been investigated primarily in materials research for potential applications requiring chemical stability and thermal properties distinct from conventional oxides. While not yet commercialized at scale, YAlS₂ belongs to a class of materials explored for specialized refractory, electronic, or optical applications where sulfide-based ceramics offer advantages over traditional oxide counterparts.

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.
