· JVASP-10131· Hg2SeO4

Mercury selenate (Hg₂SeO₄) is an inorganic ceramic compound containing mercury and selenium elements in oxidized form. This material is primarily of research and academic interest rather than established industrial production, studied within the broader context of heavy-metal selenate ceramics for understanding crystal structure, ionic conductivity, and solid-state chemistry. While not commonly specified in mainstream engineering applications, selenate ceramics of this type are investigated for potential use in specialized contexts such as radiation shielding, high-temperature ceramics, or experimental electrochemical devices, though superior alternatives typically exist for commercial deployment.
