Lead oxide is a chemical compound with the formula PbO, commonly found in two forms: red lead (Pb3O4) and litharge (PbO). It is a dense, yellowish to reddish crystalline solid, often used as a pigment in paints, ceramics, and glassmaking due to its vibrant color and opacity. Lead oxide is also crucial in the production of lead-acid batteries, where it serves as a raw material for manufacturing battery plates. Beyond industrial uses, it has historical significance in traditional medicines, though its toxicity limits such applications today. Lead oxide's properties, including its high density and resistance to corrosion, make it valuable in diverse applications, but careful handling and disposal are essential due to its hazardous nature to human health and the environment.
