· JVASP-19266· Al2Sb2O7

Al₂Sb₂O₇ is an antimony-aluminum oxide ceramic compound belonging to the pyrochlore or defect-fluorite family of oxides. While primarily of research interest rather than established industrial production, this material is investigated for applications requiring high thermal stability and chemical inertness in oxidizing environments, with potential relevance to advanced refractory systems and functional ceramics where antimony oxides provide specific electrical or optical properties.
