Lead sulfite (PbSO₃) is an inorganic ceramic compound composed of lead and sulfite ions, belonging to the class of heavy metal sulfite ceramics. While not widely used in mainstream engineering applications, this material has been investigated in research contexts for specialized applications leveraging lead's high density and radiation-shielding properties, though modern engineering practice increasingly favors lead-free alternatives due to toxicity concerns and regulatory restrictions on lead-containing materials.
