· JVASP-56681· KNiAsO4

KNiAsO4 is an inorganic ceramic compound containing potassium, nickel, and arsenate (AsO4) groups, belonging to the family of metal arsenate ceramics. This material is primarily of research interest rather than established industrial production, with potential applications in specialized ceramics, solid-state chemistry, and materials science studies exploring transition metal arsenate structures. Engineers and researchers would examine this compound for its crystal structure properties and thermal characteristics in niche applications where arsenic-containing ceramics provide unique chemical or physical properties unavailable in conventional oxides.
