· JVASP-64369· Ba4YSe

Ba₄YSe is a barium yttrium selenide ceramic compound belonging to the rare-earth chalcogenide family. This material is primarily of research and developmental interest rather than established in high-volume industrial production, with applications emerging in optoelectronic and solid-state device contexts where its selenide-based structure offers potential advantages in infrared transmission, photonic sensing, or specialized electronic device fabrication.

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.
