· JVASP-59046· Ag2HgO2

Ag₂HgO₂ is a mixed-valence silver-mercury oxide ceramic compound belonging to the family of metal oxides with potential electrochemical applications. This material exists primarily in research and development contexts rather than established commercial production, where it is investigated for its ionic conductivity and redox properties in electrochemical devices. The silver-mercury oxide system is notable for its potential in battery chemistry and catalytic applications, where the mixed oxidation states of silver and mercury can facilitate electron transfer and ion transport.
