· JVASP-155355· BaLi2GeS4

BaLi₂GeS₄ is a mixed-metal sulfide ceramic compound combining barium, lithium, and germanium in a sulfide matrix, belonging to the family of chalcogenide ceramics. This material is primarily of research interest for nonlinear optical and infrared photonic applications, where sulfide-based ceramics offer transparency in the mid-infrared spectrum and potential for frequency conversion devices. Its combination of elements suggests investigation for laser optics, photonic windows, and potentially solid-state electrolyte development, though industrial adoption remains limited compared to established alternatives like ZnSe or diamond.

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.
