· JVASP-128840· HoAs5

HoAs₅ is a rare-earth arsenide ceramic compound combining holmium with arsenic in a 1:5 stoichiometry. This material belongs to the family of rare-earth pnictide ceramics, which are primarily of research and specialized academic interest rather than established industrial use. HoAs₅ and related rare-earth arsenides are investigated for potential applications in high-temperature thermoelectrics, semiconductor research, and specialized optical or magnetic applications, though commercial deployment remains limited compared to more mature ceramic systems.

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.
