Mercury sulfate (HgSO4) is an inorganic ceramic compound historically used in electrochemistry and analytical chemistry applications. Its primary industrial use has been in mercury cell chlor-alkali processes for chlorine and caustic soda production, though its application has substantially declined due to environmental and health concerns associated with mercury. The material is notable for its electrical conductivity properties in electrochemical cells, but modern practice has largely shifted to alternative technologies using membrane or diaphragm cells to eliminate mercury exposure risks.
