· K4 As4 O8

K₄As₄O₈ is an arsenic-containing oxyanion compound belonging to the family of potassium arsenates, a class of inorganic semiconductors with layered or framework crystal structures. This material is primarily of research interest rather than established industrial production, studied for potential applications in solid-state electronics, photocatalysis, and specialty glass formulations where arsenic oxide semiconductors show promise for wide bandgap behavior and optoelectronic response.
