· JVASP-18926· LuS

Lutetium sulfide (LuS) is a rare-earth ceramic compound belonging to the lanthanide chalcogenide family, characterized by strong ionic bonding between lutetium and sulfide ions. While primarily studied in research settings for its optical and thermal properties, LuS appears in specialized applications requiring high-temperature stability, luminescence, or neutron absorption in nuclear environments; its rarity and synthesis complexity make it most relevant to researchers and engineers developing advanced ceramics rather than mainstream industrial manufacturing.

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.
