ceramic

· JVASP-25611· KBa4Sb3O

KBa₄Sb₃O is an inorganic ceramic compound containing potassium, barium, antimony, and oxygen. This material belongs to the family of mixed-metal oxide ceramics and appears to be a research or specialized compound rather than a widely commercialized engineering ceramic. Such quaternary oxide systems are of interest in materials science for their potential in electrical, thermal, or photocatalytic applications, though this specific composition remains rare in conventional engineering practice.
