· JVASP-12496· KAs4IO6

KAs₄IO₆ is an inorganic ceramic compound combining potassium, arsenic, iodine, and oxygen into a crystalline oxide structure. This is a specialty research ceramic with limited commercial production; it belongs to a family of mixed-metal iodates and arsenates studied primarily for their structural properties and potential functional applications in solid-state chemistry. The material is notable for its relatively high density and moderate stiffness, making it of interest in applications requiring chemically stable, non-organic frameworks.
