PbSO4

Lead sulfate (PbSO₄) is an inorganic ceramic compound formed primarily through chemical precipitation or as a corrosion byproduct in lead-acid systems. It appears in industrial applications as a secondary phase rather than as a primary engineered material, most notably in lead-acid battery electrodes where it forms during discharge cycles, and historically in radiation shielding formulations and specialized pigments. Engineers encounter PbSO₄ primarily when managing degradation mechanisms in electrochemical systems or when specifying materials for environments where lead compounds must be contained or controlled.
