· JVASP-153011· KLaGeSe4

KLaGeSe₄ is a rare-earth-containing chalcogenide ceramic compound combining potassium, lanthanum, germanium, and selenium elements. This is a research-phase material primarily investigated for infrared optical and photonic applications, where its wide transparency window in the mid-to-far infrared spectrum makes it potentially valuable for specialized optical systems that require transmission beyond conventional glass limits.

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.
