· JVASP-9589· HgC2O4

Mercury oxalate (HgC₂O₄) is an inorganic ceramic compound containing mercury and oxalate ions, primarily encountered in laboratory and specialized research contexts rather than widespread industrial production. This material belongs to the family of heavy metal oxalates and is of interest in materials science research for understanding crystal structure, thermal properties, and chemical stability of mercury-based compounds. Due to mercury's toxicity and the material's limited thermal stability, practical engineering applications are restricted; however, it may be studied for fundamental research in solid-state chemistry, historical pigment analysis, or specialized analytical applications where its unique phase behavior is relevant.
