· JVASP-9555· Ca2Sb2O5

Calcium antimony oxide (Ca2Sb2O5) is a dense ceramic compound belonging to the mixed-metal oxide family, composed of calcium and antimony in a fixed stoichiometric ratio. This material is primarily investigated in research contexts for applications requiring high-density ceramics, optical properties, or specialized electronic functions; it is not widely established in mainstream industrial production. The compound's potential lies in niche applications such as opacifiers in glass systems, radiation shielding materials, or as a component in advanced ceramic formulations where antimony-based oxides provide unique thermal and chemical stability characteristics.
