Mercury arsenate (HgAsO4) is an inorganic ceramic compound containing mercury and arsenic oxyanions, classified as a heavy metal oxide ceramic. This material is primarily of historical and research interest rather than modern engineering use; it appears in legacy applications including certain pigments, preservatives, and analytical chemistry reagents, though most such applications have been phased out or restricted due to mercury and arsenic toxicity. Engineers would rarely select this material for new designs, as safer alternatives exist for virtually all former applications, and regulatory restrictions on mercury in most jurisdictions make procurement and disposal problematic.
