· KBaAsSe3

KBaAsSe₃ is a quaternary chalcogenide semiconductor compound combining potassium, barium, arsenic, and selenium elements. This material belongs to the family of complex semiconductors engineered for infrared (IR) optical and photonic applications, where its band gap and transparency windows in the mid- to far-IR spectrum make it of research interest. While not yet widely commercialized, materials in this chemical family are investigated as alternatives to conventional IR optics and potential nonlinear optical components for specialized photonic systems.

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.
