· JVASP-9564· Mg2Sb2O5

Mg₂Sb₂O₅ is an inorganic oxide ceramic compound containing magnesium and antimony oxides, belonging to the family of mixed-metal oxides. This material is primarily investigated in research contexts for potential applications in thermal management, electronic device insulation, and specialized refractory systems where its oxide stability and moderate mechanical stiffness offer benefits. While not yet widely deployed in mainstream industrial production, materials in this family are of interest to engineers developing high-temperature ceramics and functional oxide composites where antimony-containing compounds can provide specific dielectric or thermal properties.
