LaS2
ceramic· JVASP-85192· LaS2
Lanthanum disulfide (LaS₂) is a rare-earth ceramic compound that belongs to the family of lanthanide chalcogenides, materials combining rare-earth elements with sulfur. This compound is primarily of research and specialized industrial interest rather than a mainstream engineering material; it is investigated for applications requiring specific optical, electronic, or thermal properties inherent to rare-earth sulfide systems. LaS₂ and related lanthanide sulfides are explored in optics, solid-state chemistry, and emerging photonic or thermal management applications where the unique electronic structure of rare-earth elements can be leveraged.

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.
