· JVASP-13047· K4Sb2O3

K4Sb2O3 is an inorganic oxide ceramic compound containing potassium and antimony, belonging to the family of mixed-metal oxides. This material is primarily of research interest rather than established industrial production, with potential applications in functional ceramics where antimony oxides are valued for their electrical, optical, or catalytic properties. Engineers would consider this compound in exploratory work on advanced ceramics, solid electrolytes, or photocatalytic systems where the specific potassium-antimony oxide chemistry offers advantages over conventional alternatives.
