· Na4Br2O

Na₄Br₂O is an inorganic ceramic compound containing sodium, bromine, and oxygen. This material belongs to the halide-oxide ceramic family and appears to be primarily of research or specialized industrial interest rather than a widely commercialized engineering ceramic. While limited in mainstream applications, materials in this chemical family are investigated for their ionic conductivity, optical properties, and potential use in electrochemical devices, though Na₄Br₂O specifically remains uncommon in established engineering practice.
