K3GeSe3 is a ternary chalcogenide ceramic compound combining potassium, germanium, and selenium elements. This material belongs to the family of layered chalcogenide ceramics, which are primarily of research interest for optoelectronic and solid-state applications rather than established commercial production. The material is investigated for potential use in infrared optics, nonlinear optical devices, and solid-state ion conductors, where its chalcogenide structure offers advantages in transparency to mid-to-far infrared wavelengths and ionic transport properties compared to conventional oxides.
