· JVASP-109090· YbAs3

YbAs₃ is an intermetallic ceramic compound combining ytterbium and arsenic, belonging to the rare-earth arsenide family of advanced ceramics. This material exists primarily in research and specialized applications due to its unique electronic and thermal properties characteristic of rare-earth compounds. YbAs₃ is of particular interest in condensed matter physics and materials science for studying strongly correlated electron systems and potential thermoelectric or high-temperature applications, though industrial adoption remains limited compared to more established ceramic families.

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.
