· JVASP-132434· AsS31

AsS31 is an arsenic sulfide ceramic compound, part of the chalcogenide ceramic family known for optical and electronic properties. This material is primarily of research interest rather than established commercial production, with potential applications in infrared optics, photonic devices, and specialized electronic components where its unique optical transmission characteristics in the infrared region are leveraged. Engineers consider chalcogenide ceramics like AsS31 when conventional optical materials (silica, fluoride glasses) cannot meet infrared wavelength requirements, though material availability, toxicity handling, and processing challenges typically limit adoption to specialized aerospace, defense, and photonics research contexts.

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.
