ceramic· JVASP-147614· Ba4Ge2Te5Se3
Ba₄Ge₂Te₅Se₃ is a mixed halide-chalcogenide ceramic compound combining barium, germanium, tellurium, and selenium. This material belongs to the family of complex chalcogenide ceramics and is primarily investigated in research contexts for its potential in infrared optics and solid-state radiation detection applications. The combination of heavy elements (Te, Se) with germanium provides tailored optical transparency in the infrared spectrum and potential scintillation properties, making it of interest for next-generation infrared windows, thermal imaging systems, and radiation sensing devices where conventional materials fall short in performance or cost.

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.
