· JVASP-12091· Au2Se2O7

Au₂Se₂O₇ is an inorganic ceramic compound containing gold, selenium, and oxygen, belonging to the family of mixed-metal oxides and selenates. This material is primarily of research interest rather than established industrial use, with investigations focused on its potential as an optical, electronic, or catalytic material given the presence of noble metal (gold) and chalcogen (selenium) components.
