As₄Se₃ is an arsenic selenide ceramic compound belonging to the chalcogenide glass and crystalline ceramic family, characterized by strong covalent bonding between arsenic and selenium atoms. This material is primarily investigated in research contexts for infrared optics, nonlinear photonics, and solid-state physics applications, where its optical transparency in the mid- to far-infrared spectrum and potential for glass formation offer advantages over conventional optical ceramics. Engineers consider arsenic selenide compounds when designing infrared windows, laser optics, or photonic devices where wide transmission bands and chemical stability in harsh environments are required, though availability and cost typically limit adoption to specialized research and defense applications.
