· JVASP-3780· LuSBr

LuSBr is a rare-earth halide ceramic compound combining lutetium, sulfur, and bromine. This material belongs to the family of ternary chalcohalide ceramics, which are primarily investigated in materials research for their potential in optoelectronic and solid-state applications. LuSBr and related compounds are not established in high-volume industrial production but show promise in research contexts for applications requiring specific electronic or photonic properties characteristic of rare-earth ceramics.

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.
