· JVASP-25632· KBiP2S6

KBiP₂S₆ is a ternary sulfide ceramic compound belonging to the metal phosphorus sulfide family, combining potassium, bismuth, phosphorus, and sulfur elements into a crystalline structure. This material is primarily of research interest for nonlinear optical and photonic applications, where layered sulfide ceramics show promise for frequency conversion, infrared sensing, and solid-state laser technologies. KBiP₂S₆ exemplifies an emerging class of compounds engineered for mid-infrared transparency and potential ferroelectric or piezoelectric behavior, positioning it as an alternative to established oxide ceramics in specialized optical systems where sulfide-based transparency windows and chemical stability are advantageous.
