· JVASP-13104· KAsO2

KAsO2 is an inorganic ceramic compound containing potassium, arsenic, and oxygen. This material belongs to the arsenic oxide family and is primarily of research interest rather than established industrial production, with potential applications in specialized ceramics and materials science investigations. The compound's layered crystal structure and relatively low exfoliation energy suggest possible utility in two-dimensional material research or as a precursor for engineered ceramic composites, though its arsenic content typically limits adoption to controlled laboratory and industrial settings where toxicity can be managed.
