K2PbS2O8

ceramic

· JVASP-85764· K2PbS2O8

K2PbS2O8 is a lead-containing ceramic compound belonging to the sulfate family, combining potassium, lead, and sulfate anions in a mixed-valence structure. This material is primarily of research interest for specialized applications requiring lead-containing ceramics, particularly in optical, electronic, or radiation-shielding contexts where lead's atomic properties are advantageous. Engineers would consider this compound when conventional lead-free alternatives cannot meet specific performance requirements, though its use is increasingly constrained by lead toxicity regulations in consumer and environmental applications.
