· Na2HgO2

Sodium mercury oxide (Na2HgO2) is an inorganic ceramic compound containing mercury, belonging to the family of metal oxides used in specialized chemical and materials research. This material is primarily of research or historical interest rather than mainstream industrial use; it has appeared in studies of mercury chemistry, solid-state physics, and ceramic material synthesis. Engineers would consider this material only in niche applications requiring mercury-containing compounds, such as certain electrochemical systems or specialized catalytic research, where its unique chemical properties provide advantages over conventional alternatives.
