Mercury selenate (HgSeO₄) is an inorganic ceramic compound containing mercury, selenium, and oxygen. While not commonly encountered in mainstream engineering applications, this material belongs to the family of metal selenate compounds that have been studied primarily in materials research contexts for their crystalline properties and potential optical or electronic characteristics. The compound's notable density and stiffness reflect the heavy metal content typical of mercury-based ceramics, though practical engineering use remains limited due to toxicity concerns and the availability of safer alternative materials.
