· JVASP-36292· LuAs

LuAs is an intermetallic ceramic compound composed of lutetium and arsenic, belonging to the class of rare-earth pnictide ceramics. This material is primarily of research and specialized applications interest rather than a commodity engineering material, with potential applications in high-temperature electronics and semiconductor research due to the unique properties associated with rare-earth compounds. LuAs represents an emerging material family being investigated for niche applications where the combination of rare-earth and pnictide chemistry offers advantages in extreme environments or specialized device geometries.

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.
