Sodium mercury phosphate (NaHgPO₄) is an inorganic ceramic compound containing mercury and phosphate phases, primarily of research and historical interest rather than current commercial production. This material belongs to the family of heavy metal phosphates and has been investigated in materials science contexts for specialized applications requiring mercury-containing phases, though modern engineering practice has largely moved away from mercury-based materials due to toxicity and environmental concerns. The compound's notable characteristic is its relatively high density, making it potentially relevant for applications requiring dense inorganic phases, though it is not commonly specified in contemporary engineering design due to mercury's regulatory restrictions and hazard profile.
